It's a crime this man doesn't get more views

Haven’t met anyone who does as thorough of a job as Matt! Whether remote or in person he’s always got my stuff dialed in and running great!

Great vid - the Chopacabra is a play on the word Chupacabra - which is Spanish for “goat sucker”. It’s a cryptid animal in Texas and the American Southwest/Mexico. Most likely a coyote with mange. Now if a Louisiana shop would come out with the WampusCat Cam we’d be all set!

You did it again with another really informative video. Really like this type of video where you take your time to explain why you adjust a parameter or not to adjust a certain parameter. Thanks Matt.

Thanks again for teaching! I used your "Burn out tune" worked great! I hope your channel keeps growing, you deserve it!

Bro thank you for taking the time for all this! It came in handy subscribed!!

Thanks for the great videos i learned a lot from your videos as a new tuner also my customer loves the 6l80 tune i learned from you and i fine tuned it more and it came out great also its nice to see someone share there knowledge keep up the great work and videos i know its tough in this industry i have my own shop now for almost 20 years and i keep increasing more things to offer the customers and tuning things now adays makes the engine and transmissions last longer and perform way better i hope more people find you and learn and listen to what you say and show the information you put out is spot on in my view

Matt. Thank you so much for doing these videos. I’ve learned so much from your content in the last couple months. Actually just bought an MPvi3 last week and already wrote the first tune to my truck. Thinking about turning this into a side hustle down the road. Much appreciated!

I've tuned a couple gen4 chopacabra 5.3s. I'm pretty impressed have easily they are to tune. Easy to make idle and easy to make "chop" without raping the overspeed and underspeed tables

You came through like you said would. Thanks for listening to us and making this video. This should clear up some of my questions

I was interested when I saw your contribution to help Nate in tuning that red supercharged truck of squirrels when I saw he called you. I realized at that point dr. Tune em all was human. Subbed immediately ❤

Awesome amount of info!! This guy deserves millions of views! Thank you sir!

So glad you made a couple uploads today. Gives me something to do while I wait on a truck and trailer because I spun a bearing in my saabaru. It was a reused popped fozzy xt motor with drop pistons and reused headbolts in the vein of sloppywiki. Lasted 100k so I ain’t mad, just stranded lol. 4 years at 26 psi ain’t bad for just trying to prove a point to my coworkers lol.

So I plan on doing the AFM/DOD delete on my 2012 gmc Sierra. I was considering getting HP tuners before even getting my 2012 Sierra. I was planning on getting it for my 2001 Sierra. Looks like the HP Tuners program is a must have in today’s world. I wish i bought it 5 years ago maybe i wouldn’t be so nervous now.

Thanks for all you share. I'm a transmission builder and often see the yoke leak and damage the trans

This video is so good I feel like it should come with a link to a "KZfaq Certified Tuner" certificate. lol. No, I'm smart enough to know that I have no idea what I'm doing. I am leaving Iraq in a few days and heading home to Fort Worth and am going to get the MPVI3 to troubleshoot some 6L80 2-3 shift problems on my 2013 Sierra. Pretty sure it's mechanical but I want to check it out electrically first and after watching your videos I feel confident that I can read it and not screw it up. Thanks for all the awesome videos and take care man!

Im learning by watching you!

I see a video and I like it 👍 no questions asked, I’m on the path do find out what I want to do as a career and you make this career path much more possible 🙏 much love from cali.

Always good content when you post a video! Finally making some headway on my dad’s C5. I will have to show him the part where you say we can’t smell rich or lean because he keeps saying it smells too rich at idle 😂

Best tuner I have ever seen, thank you so much ❤️

Great video Matt!!! The info was awesome and the pace you chose I thought was perfect.

Thank you for the video by far very knowledgeable and we the people appreciate it

Great stuff! i was already gonna watch an older video today, now i don't have to.

man this is what i needed! thanks man, youre the real mvp now

thank you for making these videos man! this stuff really does help us at home tuners just learning on our own stuff. im on a torque based gen4 e78 ecu so its alot more frustrating than the e38 for me to figure out how to get dialed

The coolant leak is at the "Y" connector coming right off the water pump... Run your fingers on the UNDERSIDE of the "Y" connector and when it comes back wet-you have found your leak. The trans is leaking fluid through the drive shaft yoke because the transmission has been replaced, or rebuilt, and the is now missing the output shaft SLEEVE that seals to the yoke inside the extension housing. Very easy fix but will require that the shaft come out, and extension housing be removed to install a sleeve... OR, just pull the shaft, and plug the hole in the yoke... Either way works.

Just to make a correction here. Matt says in order to find the EQ ratio the math was 14.7 / 12.8 But really you don’t use 14.7, you actually make sure you use your set/commanded AFR in the tune. So if your stoich is set to 14.1, then the math would be 14.1 / 12.8 = commanded EQ. Thought I’d point this out. 👍

Very informative, I really appreciate all your effort. Thank you very much.

There's an internal o-ring that basically seals the front of the driveshaft yoke, they go bad and leak into the splines, then out that weep hole. It's an easy $5 fix, just not very common knowledge that o-ring is in there.

2:20 The truck has"243" LS cylinder heads which originally came on the 2001-2004 Corvette C5 Z06. Just an observation that it no longer has the factory "706" LS heads. So it's a little less "stock" than some might think.

Great video mate. Personally I use EFILive, but the principles are the same. Interesting approach to the base and coast spark tables which I like and will test myself. Interested to know how you came to trust the NB so much over the WB at idle/cruise?

I love all the videos, I would love to sit more on the Gen 3 stuff because I know Gen 3 vs 4 is different. I was trying to tune my truck and somehow, someway. I screwed it way up. I'm not sure if i should be tuning for the MAF or VE table. I know when I start my truck, you can hear the intake pulling ALOT of air, then STFT kick in and bring them back down. However love all the videos, Keep them coming.

Love the video man, very helpful

Excellent video !

Awesome video man

I’m not unintelligent by a long shot, and I’ve tuned with other softwares before. Nothing American but man, hp tuners proves to me over and over that’s it’s overly complicated. You seem to know it extremely well but as someone that’s new to it, I don’t wanna touch it tbh. I just feel like it could be 100x simpler. There are a million tables 😂😂 I’m not gonna give up on learning it but I doubt I’ll ever actually tune something using it. I’d much rather tune a standalone system. lol great video though! 🔥

hey man love the videos, literally the only channel im a member of. id like to pick your brain on my tune for my btr stage 3 truck cam. followed you through your process but im at the point of needing to tune vve, im watching my stft try and pull 25-30% at idle. do you suspect a vacuum leak or does this seem roughly ok? 2013 chevy silverado 1500 lc9 5.3l gen 4 e38 pcm. ill be getting a wideband soon, just got the truck back up and running

Best video Matt

I’m actually looking at doing this to my truck. It still has that AFM crap and VVT.

When I make an appointment for an in person dyno/tuning session. That means you do the tuning and I get to watch?

I have a LQ nine in a square body Chevrolet. I had somebody do the wiring for me, and now I lose throttle response periodically throughout any portion of throttle usage. It may be at wide open or it could be at an Idle. I can kill all power to the system, and the throttle starts working again for how long I never know could be second it could be hours. It is, I drop my Wire system, and the pedal has two rows of pins in it.

The transmission driveshaft yoke had a hole in it from the factory. It leaks when you overfill the trans

2016+ 4x4 trucks driveshafts are rated for 125

Ayo, Matt, the tuning guru! Saw you Cleetus video. Much love from Texas, bro! ✌️

Do you have a video or can you do a video walking through a mafless tune the same as what you did here?

Please link a local tune shop in Los Angels, I live in Glendale CA.

The mis fire counter says read only

I put an aftermarket stall converter in my truck and now whenever the torque converter should lock out I get a TCC stuck off error code. Is this something in the tune I need to change or my transmission have a problem?

Matt, when it comes to using the STFT data, in the event of remote tuning or even in person where a wideband isn’t being used……..At what point is the STFT data for the ve/maf tables essentially “not good”? I would assume that when the vehicle enters OPEN LOOP that will present a problem?

That 5.3 made a bit more than my 6.0 bored 30over, 243 heads, 50lbs injectors, long tube headers & BTR stage 2 truck cam my 6.0 made 299hp.

So got a question what would you recommend as a "grunt cam" Specs 400-550 hp and torque under 5500 rpm Looking for my truck its a 14 Silverado 2500 with the 6.0 Looking for cam, spring, and pushrod package

How similar is truck Norris to this cam

Need an estimate on a tune please...

If i want a remote tune with you what all do i need to get? Currently dont have hp tuners

Great video ,how much would somebody pay for this?

Any 10 speed love?

Where can u order those headers?

Does it pay to dial in the nb's after header installation to make up for the error caused by downstream relocate? Say you have nb- wb sensors that are within >2% behind a stock manifold, then after headers the nb's go way out of wack...10+ percent. In this video say the wb is correct, does that mean the truck is running ballpark 10% lean in CL or if nb are correct is PE way off?

When you disable LTFTs during tuning do you re-enable them once you're done? And I'm curious why you ditch them in the first place, I probably missed the explanation in a previous video.

If I change my Stoich to E10 14.12, and I tune cruising and idle using STFT's, are the O2 sensors going to be properly targeting 14.12?

Matt. New subscriber here. I just got a 2010 Tahoe with the 5.3 and 215k miles. I can’t stand the DOD. I’m a big Toyota guy but would not mind building the Tahoe to at least have as much or more power than my 5.7 Tundra. Any suggestions on where to start or how much of an investment it might take? I’m not naive. I know that a person can spend anywhere from a couple of grand to probably 30 or 40 grand. Just kind of looking for a starting point and some advice. Thanks.

Do you tune after the break in cycle or during? Curious for my lt1 I'm building and I'm putting a slightly bigger cam in and not sure about running a tune during the 20 min 2k rpm break in but there in lies my question

GRG has a Gen 5 EEV/MAF tunning at the same time Function....thing IDK. it tunes them both at the same time. my question is, in your function, do you use EQ Error (which as far as I can tell requires the wide band O2 to work) in your stuff? i still learning but have a bone stock truck, other than cam, and didnt want to drill a hole in the factory down pipe. is there a real way around this, and still do what your doing? If a have too, I have to, but im just curious. I have aslo been told that the tail pipe widebands have some unavodable errors in them.

Can I buy tune files from you? I am starting to get busy with swaps but I struggle to find the time to practice my tuning..

what stall you recommend for a truck norris cam in a 2000 5.3?

Cleetus sent me

Would this work in a l96 6.0 as well? or no. If not could you do one of thoes trucks when u can?

I don't think i agree that even with a stock cam a converter makes it drive nicer it might be faster but i have a restalled stock converter in my stock silverado its supposed to be like 2400-2600 and its cool but a stock converter stall is better i think for most people

Can you tune an AWD Escalade?

Damn.. perfect timing on ur video, I'm putting the same cam in my truck tomorrow. But it's a 2015 tho. How much different is the tune compared to that year to a 2015?

Matt, do you also recommend leaving LTFT disabled permanently?

Have you ever tuned the TSP N/A Bald Eagle cam ? Do you think it would make good power ?

They’ll put the word Chop on anything huh

Matt, if we are doing MAF or VE Tuning at Idle/Part Throttle do we need to disable Power Enrichment? Does it even matter? Also, Is it safe to say that all of these vehicles need to have Stoich flatlined to 14.10?

you do remote tune? l83 got a 6l80e with a "high stall". long tube headers and l86 ported intake/tb. my local tuner straight up told me he don't know automatics and to go to another province tuner where they run totally different gasoline. be ready for the worst gasoline you might ever have tuned... British-Columbia gasoline.. if you are up to the task id book some dyno time.

Turning off the long-term fuel terms in my opinion is just the laziest way of tuning. Didn't you say yourself just a couple minutes prior to that its best to keep all of the original features working if possible" don't disable things...... I understand if you're in a scenario where belong to headers make one o2 sensor read a lot worse than the other but that's extremely rare and easily fixable. Almost every vehicle that comes to my shop that was tuned by somebody else has the fuel trim turned off and usuall it's a really basic tune that had absolutely no reason to have the fuel trims turned off. it cuts their mileage in half and causes them problems returning to idle. I can tell you've got a lot of experience doing thiso I want to know why you think it's necessary to turn off the fuel trims.

You went to fast I’m trying to learn how to tune 😂

Don't know if you have time to respond. Im oldschool. This is new to me. I put this cam/springs and a 3000 stall in my truck. Problem is i cant find a thorough tuner like you. What can i do? Please help

You as a tuner what would be the best cheapo under 500 dollar plug in gas tuner

The battery, exhaust, and other basic issues should have been fixed before the cam was installed.
