Pre DEF Diesels have actually increased in value.

Thanks for this! I feel like I can communicate w my bf a little better instead of just standing there nodding while everything he says goes flying over my head!😂

I commend you for making a video on the subject as enforcement of emissions equipment on diesels is being ramped up.I am a diesel mechanic I work on mostly heavy trucks Macks international freight liner,I owned 4 diesel pick ups myself,Once the DPF came out I stopped buying diesel trucks. Some of your information is a little bit incorrect and I would like to make you aware of it. You stated that DEF fluid was brought out because people were complaining about poor fuel mileage.DEF fluid came out because there was no other way to reduce NOX emissions enough to meet tier 4 final Emissions levels without it. International Did not use def fluid until 2015 they use a very high percentage of EGR from 2011 to 2014 to supposedly meet tier 4. final emissions.Their trucks did not meet emissions standards ,eventually international was fined a tremendous amount of money, I believe that the only reason they let the company stay in business is because they were such a high percentage of their trucks that are school buses and municipal trucks and if the company was put out of business it would have a huge effect on the entire trucking industry.Not only did they not make the emissions without it the EGR coolers failed an alarming rate because you’re running a very high percentage of egr was causing egr coolers to crack sometimes every 8-10,000 miles, and it was causing engine oil to be contaminated very quickly. By using Def fluid, The auto makers were able to drastically cut the amount of EGR needed this helps keep the engine oil cleaner , and reduce the pressure on the EGR cooler and cooling system of the engine.The other mistake you stated was that DEF is injected while the truck is in regen or burning off, That is true but DEF is also injected anytime the engine is up to temperature it’s injected slowly insteadily. The systems are getting better they are now installed on new trucks as a module containing the DIesel oxidizing Catalyst,The DPF and the DEF injector nozzle. One area where big trucks and light pick ups differ is the way they inject the diesel fuel large trucks use what’s called a doser behind the turbo charger,I think the Duramax uses this as well I know that early Fords used extra fuel in cylinders seven and eight, That just washed down those cylinders and ate the rings. The doser injector is a way better system. In United States while it may be legal locally in certain areas do not have an emissions inspection it is still illegal in all 50 states to remove any emissions control device from any vehicle for on road purposes. Here in New York commercial truck inspectors know what to look for if you have a 2008 and newer truck and you’re right rear fender has soot on it,And you’re driving in Rockland County or further south where they have DEMA ,which is “diesel emissions metropolitan area” regulations, you may get pulled over and inspected. I personally can’t stand the DEF systems, They have caused our large plow trucks to go down like you said for weeks at a time, our trucks are kind of important m since they’re plowing town roads are they useless sitting on the side of the road idling with a triangle on the dash board. .I have to go out with a scanner and do a forced regen ,Which can take up to 45 minutes in order to just be able to drive the truck back to the shop. Unfortunately this happens with brand new trucks like you said the cold weather and the roads are are not friendly with DEF heaters or lines.

Only one reason not to delete your truck: Government playing daddy and stealing your money any way they can.

I recently did mine. EGR, pipes, throttle and re-program. I am amazed how much better this rig runs now. Now I'm freaked out about the grid heater, so I plan to yank that out as well and install a GMC type heater in the intake horn. I do a lot of rural of highway driving, no city. I average 21.5 MPG if I baby her. I did it because the EGR was failing, soot was filling up my engine oil, temps were also running high. The delete fixed everything.

Gotta correct a couple things on the oe emissions side. The dpf is for particulate matter(soot). The regen process raises the temp in the dpf to burn off that soot. On Ram trucks, this is done if too much differential pressure is sensed across the dpf and on an engine hours basis. On my def equipped trucks, this was about every 24 engine hours. On my pre-def Rams it was less than every 10 engine hours. DEF is injected into the catalyst after the dpf & is not used for cleaning the soot or in the regen process in any way. It reacts with the catalyst to remove NoX emissions. This allows for less egr to be used on def equipped trucks. Less egr = less soot= less regen’s.

That’s exactly what happened to me. I was working out of town in northern Minnesota this winter. Truck threw a code for egr valve. I had to drive it at 55 max speed for a month until I was off work and it warmed up to be able to work on it. Needless to say I’m gonna off road it all the way back to western Pennsylvania!

Damn!! Great vid! I wish I had watched this BEFORE I bought my 2013 F350. My MPG is a dismal 15-16! I drive professionally so I'm not mashing down on the acceleration. Maybe time to trade in for a pre-def one.....

18 Cummins it has helped fuel mileage 5-7 mpg also my engine oil is cleaner longer. Power is all in the tune. Thanks for video. 👍

I followed your video as best I could and deleted my 2014 Cummins this week. Waited for the warranty to expire. Installed EFI Live tunes, S&B Cold Air Intake, deleted CCV, DEF and EGR. Thanks for the video! Extremely helpful!

Great video. I learned a lot on this now. I wish I watched this while I went to look at a duramax. Thought guy was lying about the tune for delete and why it was only running 40mph. I lost out on nice truck.

Very good video. Thank you. Live in Alaska where it also gets -40F. Now seriously thinking about deleting.

Thank you for making this video. It helps us to be in the know...

I have deleted my emissions on my 6.4 diesel f450...now it's the most beautiful truck reaching speed limit quickest no more engine sweetening because it's high temperature,no more regenerate with a lot black smoke, no more esues so aften and more saving fuel..now I'm very happy...

Deleted my LMM after warranty was up.. EGR block plate, MBRP Downpipe, 4 inch Flo Pro Truck runs cooler when towing, gets a little better mpg..

I have an 2011 f350 6.7 non-delete with nearly 400,000 miles on it and no issues other than a starter, oil pressure sensor, small radiator leak from a round rubber gasket that broke.. truck runs great with tons of power and torque and wants to keep going..

DEF has nothing to do with cleaning the DPF. DEF reacts with the exhaust to reduce NOX. DPF regen is what burns off the soot converting it down to ash. 😉

Best part of my deleted lml no more filling the damn def tank! Also I’m getting 4mpgs better, and I will agree removing the egr from the duramax sucks! But whole process took 7hours of cussing 90% on the egr for sure!

Great video. Glad you got the merchandise site up.

Wonderful video ! Love all the explanations and parts you show. Extremely helpful

I came across your video looking up pros and cons of egr deletes on gas cars. I hit like because your video was well-informed and you passed that on. Also, I’m Canadian, and I like Canadian content. I had a diesel but sold it after too many check engine lights all emissions related; nothing to do with drivability. All were going to cost thousands so I unloaded it. If I did buy a diesel truck or car again I’d look for pre 2008 or whenever DPFs or DEF came out, no matter the miles. I’m in favour of clean air but I confess to liking the smell of unprocessed diesel exhaust since it reminds me of trains.

Even if you don’t gain much in fuel mileage costs with a delete, you will recoup some money by not expending cash for Def!

Awesome informative video. A lot of misconceptions out there.

Dude I’m 3 minutes in and I already learned so much thanks man

Just finished a full delete on my LML. Used your videos and info a ton. Then had to replace my turbo 3 weeks later due to leaking seals putting oil into the exhaust. I was able to do it myself with Dark Iron Diesel videos! You’re the man. Buying some merch for sure.

My '14 Cummins went from 8-10 mpg to 15-17 mpg in town after deleting DPF and EGR. You should mention that part of the 'recycling/regurgitation' process the EPA bs on these trucks sends massive amounts of soot into your turbo! I saved mine right in the nick of time! I tried to free spin the fan and it was stopping instantly. It was f... caked in soot... I cleaned it some brake cleaner and it now sounds like a jet even with my rumble!

Thank you so much looking into buying either LML or LBZ and you helped out a lot, thanks again.

I'm glad I stumbled upon your video bc I had a 05 duramax with quadzilla tuner 3"downpipe into 4" straight pipe all the way which you know was b4 all the emission stuff, and now I have 2011 f-250 6.7 all stock so I'm new to the def fluid and all the emission sensors now and was gonna buy programmer for it then delete it down the road when can afford it but now I know it would create problems if don't do them at same time, which really makes me miss my dirty

Love your third gen Cummins mate! And if I were to buy a 10 year old plus HD diesel truck I wouldn’t be worried about warranty and emissions. I always make sure I have a backup vehicle or a vehicle for specific tasks. As much as I love the new Ram 2500+ Cummins I can’t justify $90k even for a daily driver. The older trucks are way more fun esp if it’s a manual!

I understand that by deleting voids warranty but aren't most of the problems you're going to have that you would use warranty for have to do with the whole emissions system?

I've been working in a dealership for the last ten years, as a jockey, and it's the first time I hear the term ''stealership' . now that's hot, I know they'll screw you over, I witnessed it, but the term stealership is new to me. From now on I'll be using it whenever I can. HAHAHA thanks for posting.

Another tip I would give along with the three you mentioned is upgrading the cold air intake. Thank you for your contribution. It’s stuff like this that really helps people understand! 👍🏻

My 08 LMM is fully deleted, EFI Live tuned with a DSP5 switch, AirDog 4G 165gph lift pump, stainless steel fuel lines, factory fuel filter housing fully deleted, full HSP turbo and intake piping kit, 4 inch straight pipe exhaust with 8 inch tip, fuel rail pressure relief valve delete plug, ported fuel rail fittings, and cleaned up the engine wiring harness and tucked it out of the way to hide it. It's my daily driver, tow rig, and race truck. It'll out run a 5.0 GT Mustang, gets 24mpg, doesn't smoke much either. Has a deep rumble exhaust sound with a loud turbo whistle.

There's 100% no cons in fully deleting your diesel.

Great video. I love your presentation you made the system easier to unstand for the lamen. that you opened with a little disclaimer, legendary man.

Check out Pittsburgh Power fuel catylist called "max milage". This is a catylist that changes the fuel chemistry and not just an additive. Helps burn fuel more efficiently reducing soot. Working great on my 97 power stroke, more milage and a considerable less soot build up in tail pipe. Only mods are slightly larger turbo, nothing crazy, (old one shucked) and 60hp program.

Stay Tuned! Love the deleted life good video

My only problem with the modern Diesel emissions is the EGR. If there was another way to burn off unburned diesel without redirecting it back through the engine I would be all for it. My first experience with diesel engines was with my grandfather's 89 Dodge ram. He still has it to this day and it still runs great. I remember driving it about 15 years ago and the odometer rolled over. I bought my first diesel 3 years ago and I'm disgusted it to find out that it may not even make it to 100,000 MI.

Do you have your shop open yet ! Good to see a fellow sask boy making it happen !

Awesome video. I learned a lot with all the information you gave. Thank you.

I can’t believe you’re a smaller channel, your videos are so god damn good, amazing quality, very informative, professional, must say I’m impressed. Bonus points for a fellow Canadian

I dont care if its illegal. It's my property.

You bought yourself a like and follow. Real talk is not common anymore, you done just that. Respect.

First time watching you , I learned a lot keep up the great work 🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸

Great video man! Definitely good information about how to full delete your diesel truck. I owed 05, Ford F350 6.0, I completely bulletproof my truck and done lots of upgrades, but I need little more throttle response. Do you have suggestions?

Only way to go, great info as usual

My 2016 CTD had emissions failure at 24,000 miles. Called the dealer, 10 week wait. Got them to sign a form that they would not void my warranty if I deleted. They signed it. Overnighted a delete kit. Installed. Went from 13MPG to 19MPG and it sounded mean as hell. Had Cory Willis from PPEI tune it. With the 220hp tune she screamed. If I buy another it’s getting deleted.

I deleted my 14 Cummins for the reason of cost to maintain the system. My oil after running 7k miles was like tar. Every time I cleaned the egr system it was full of soot. After deleting my truck on 60hp tune ran like the day it came of the show room floor. Haven't seen anyone tell you the cost to maintain the egr system. My dealer quoted 1,500 by the time it was done. I'll keep my delete my truck seems much happier.

When I deleted my 6.7 cummins I went from 11 mpg and went to 21mpg. I run a 120hp tune and have no smoke, I've never been happier with it

Deleted my truck. Went from 11 ish MPG TO 17 MPG. It’s 100% true. Especially with a CAI. It would probably be even better with a full intake system change.

Had a '21 duramax denali that left us stranded on a family road trip bc. of emission system, 1 year old truck. 1 year later, it had to have its particulate filter replaced under warranty. Traded in for a '23 gas denali... no more problems! And it's fast.

Best video on this out of tons watched.. thank you so much for making this clear

Drive an ‘03 6.0. I’ve had it since ‘08. I will continue to do maintenance early, to my “upgraded” EGR, studded motor. New trucks look so nice, and I could go buy one with cash, but I’ll stick with my old truck. Runs great, still sounds and smells like a diesel should. Sad where diesel trucks have gone smfh. Good, somewhat accurate video dude. Funny you had to explain what “deleting” is. And yes, you should do it, if you want a diesel that will last and not break down all the time. Or, you can go spend $80k on your new loaded truck, that runs like shit after a few months of spending tons of money on shit fuel, shit DEF, and additives for oil and fuel. Cheers to the EPA (in the US).

Def fluid doesn't burn, and is injected pretty much all the time, when it heats up in the exhaust in neutralizes/reduces the amount of NOX In the exhaust. The regen cycle is what burns the filter clean by increasing idle speed and dumping extra fuel into the exhaust. Def has not one single thing to do with burning the filter clean or increasing mpg

I agree with you the EGR is very bad for the motor and if you can delete that your money ahead. It reduces the life of your engine by half if left untouched. I don’t understand the EPA on emissions if we are going to have it then it should be a standard across the board not just some cities have it and others don’t. I hope it don’t come to that but whatever. Thanks for your vid I enjoyed it.

He's 100% right on deleting it I will speak from experience if you delete the EGR cap it off because the a little electrical motor that opens and closes the gears can become brittle and break and your EGR valve can get stuck half open or all the way open or you'll get lucky and be closed just cap it off and tune it I know this because I put a barometric pressure sensor that told the EGR to stay closed and it got stuck half open and I dissected the EGR and found that the gears were all stripped out where the motor was for opening and closing the valve no BS and this was on a semi truck same s*** is on all the pickup trucks except for my 7.3 😎

My question is, if you wait for your warranty to expire to delete your truck has the damage already been done?

Deleted my 2015 duramax because it was cheaper to do the replace the faulty egr ... didn't get any gains in milage .. but gains knowing I don't have to deal with Emmons failures in the future. Lol

Thanks for the great explanation...

This is my first time watching your video I don’t have one of those crappy Duramax diesel‘s I have a Cummins but I really liked how you came across and you explain things very well keep up the good work dude I enjoyed it I am I will keep watching you have a good one

I bought a low mileage 6.4 (50k) that had leaking coolers already and had I not taken all the shit off (egr, cat and DPF) I would be having terminal engine issue's

I don't know for sure, but I'd guess my pre delete emissions were worse than my post delete emissions. I get ridiculously better fuel economy and no matter how much throttle I give, it won't blow black smoke. So to me it seems better than factory for both performance and emissions

Def is added to the exhaust to work in conjunction with the egr and the cat to reduce NOx emissions through selective catalytic reduction, thats why the def system is sometimes called the scr system. its not for cleaning the particulate filter, the truck either cleans that through passive regeneration (naturally high egt to burn the soot out) or active regeneration (artificially high egt from extra fuel being added to the exhaust stroke) if theres too much soot load on the filter and not enough passive regen. but yah def fluid isnt for the filter and the reason it helps with performance like fuel mileage is because the engine can use less egr to reduce nox emissions which hinders power and efficiency and instead pump def into the exhaust to catalyze the nox.

After a stuck egr valve a plugged off dpf filter a def heater, def pump and worsening mileage I deleted everything and went to a 4” turbo back system , the truck is running better than new.

From TX with an 08 6.7. Delete, ALL THE WAY!!! Zero smoke along with 20+ on frwy. What's not to love?

My buddy was able to get a pretty good mileage increase after deleting and his oil stopped getting black immediately after a oil change

Thanks for the info. I found your video very helpful👍🏻

Hey video thanks for posting this and sharing. This world is true still pretty quiet no one really wants to give any information out about this. Deafly will be deleting my truck once I hit hundred thousand miles on this motor. The EGR system is such garbage and the fact that the DEF system is too.

Interesting thing about nox emissions. SpaceX emits twice the yearly nox emissions of the entire worldwide light duty diesel fleet with the rockets they launch every year.

What’s your thought about having to do it every year due to emissions? Will it harm it in anyway?

I was very impressed 👏 video thank for the video I have a 6.4 power stroke 2008 I want to delete egr I look for good kit delete I'm new in diesel trucks So I thanks full for this information

Decals! 😂 lol I’m gonna cop some merch! Nice video! Subscribed!

It's a rip of to charge so many thousands of dollars to clean a DPF filter.

Hypothetically, if you somehow permanently closed the valve without a tune, then changed your exhaust would it work?

Thanks extremely informative

My lbz lifted 6in on 35s get 17 combined mpg, I know I could get a lil bit more buttttt....... I love the sound of my turbo and I love gunning it and making noise and fast , and I tell my self I should drive better for mpg but it never happens , we are all kids at heart when it comes to the sound of screaming trucks and turbos

14.3l /100km on my deleted 2012 lml for fuel mileage.

DEF reduces nitrous oxide emissions in the scr. It doesn't increase fuel mileage.

As long as tunes are out there and piping is still made ppl will be deleting diesels as long as diesels are made. Everyone in my area panicked and diesel shops and behind the scenes ppl with tunes were swamped with ppl needing their trucks deleted. Just hope you can still get the intakes and other accessories like fuel systems.

I know this is not a buy and sell site,I have a cherry95 GMC LONG BED FOR SALE 2100$ nobody around here seems to want this thing great apolcylpse truck, you have a fantastic site and very good advice

I would love to get my 2016 dodge 2500 6.7 but I can’t find a tuner to delete it

This is exactly why I’ll never part with my old diesel truck.

Thanks teach. Good info

Awesome info it really helped me out knowing

Def fluid has nothing to due regens, or soot. Def only changes the chemical make up of your exhaust by converting harmful exhaust gasses into harmless gasses. Again DEF fluid has absolutely nothing to do with soot reductions.

"its not piss" hahah

Best pro's/cons vid on this subject I've seen. Would love to "delete" my truck, but the two big cons will prevent me from doing so. By the way, why do they call it "delete your truck," rather than "delete your DPF system?"

Awesome video. I just deleted my 2017 f250 and unplugged my egr. Do you need to install a tune to shut off the egr prior to unplugging it or should it be ok if the tune is installed AFTER unplugging?

Never did a delete, but the 2005 F550 I drove got the same 8mpg as the 2015 F550 I drive now. They're both about the same curb weight (13,000 lbs). The only difference is now I don't smell like diesel exhaust after a 10 hour day.

Deleted my LML with the 30% EFI live. Best money I've ever spent.

Great video your a pro

Helps me better understand! Thank you!

Im starting to believe these emissions on trucks was a big money grab.

I'm a firm believer if i own the truck I should be able to do whatever I want with what I own. I do understand that the manufacturer has to do right by the EPA but as the consumer it should be up to the end user what they do and don't do with what they own and pay for.

Thanks For the Video, just got a 22 Denali L5P Duramax its way too quiet, want some noise, and exhaust shops say will still be quiet due to DPF, I feel stuck, not sure what to do!

My DEF system freezes up (Canada)…dealership says internal heater is ineffective during a deep freeze. They also said an external heating pad may melt the reservoir.

Don’t need to delete your diesel if you buy a 7.3 🤷🏻‍♂️

Need to find 2020 delete tunes. No testing for emissions where I am. Police/bureaucrats don’t know anything about diesels.

No matter how you look at it the DPF systems are here to stay and the penalty is steep if you remove it. If you want a diesel pickup you just have to deal with it. A friend runs a stealth tuner that’s designed to work with DPF emissions system. If I buy a new one down the road I’ll just run the stealth tuner with DPF system. Power and mileage increase can be pretty substantial after deleting.
