Matt is the best thing that has happened to the Foxbody Mustang in a long, long time...

Is this the part where the carb guys profess their love for their screwdrivers? Lots of information, good stuff!

I wish Matt was still open

I bought used 24lb injectors from a 93 mark viii plus the mas sensor that was on the car.

Im currently working with Matt - dude is an absolute rock star. He's incredibly knowledgeable and patient. He's already got my car running so much better.!!

Best advice. Contact your tuner first. Exactly what I did and then went with the Holley Terminator X 🤘

Mathew is a good dude. Very knowledgeable. He's helped me some on my car

You gotta read the plugs also and look for detonation

OMG this was such a blessing of a video! Thank u so much for doing this. I hope u keyboard warriors and millennials listen hard to this. Matt was dead spot on with such valuable info. Probably one of the best foxbody tech talks i ever seen. Thanks again BREW2L and Matt. This is Gospel!

Glad someone is finally giving good info to people. Scaling the MAF tables for larger MAF housing and injectors is critical for making good power and overall driveability. In general a good dyno tune with street tuning to round everything out is in my opinion the best way to go on anything your building to make power.

Excellent info.

Much needed information , Thanks

More of this please.

Perfect timing on this video, answered a lot of questions I had. Thanks. Really dig the channel also.

Somehow I missed this video.. another good one! Matt and the guys @Leech motorsports are super knowledgeable!

Hey brew2L awesome video this is great for a lot of people Matt is an awesome guy I’ve worked with him and helped me a lot

Wow learned a lot in such a short time. Good stuff! Thanks gentlemen!

Good video I learned a lot thanks

Thanks for the Video on Injectors Bro.

This was extremely helpful, truly appreciate you brother!

Good info that I didn’t understand completely before. Very helpful!! Thx for the vid BREW2L

Men! This video dropped perfect time, I didn’t get a chance to ask you or Neo’s opinion last night. I feeling a hell of a lot more confident after buying 30lb injectors. If it wasn’t for this channel my shit still wouldn’t be running right lol.

Great video and interview/discussion, I loved it, thanks BREW2L! Matt Harrison, thank you so much for stopping by and educating us, we appreciate it! P.S. You also have a new subscriber Matt!

Great info.. I had always heard the SD cars couldnt be tuned.

Great information man this was a big help!

Good stuff!

Matt's generally have a lot of knowledge 😉

Thanks for featuring us on the channel, looking forward to more collabs in the future!

Love the content.

Wow simply wow thanks fir that 👍

Perfect timing for this video to come out, because I'm at the point of getting a new fuel pump, injectors, and which standalone to go with, thanks for everything, my setup is stock block 331 balance 23, Windsor Jr heads, performer efi with a V2 supercharger

Lots of good info. Very Cool Parts in Enterprise is gonna tune my microsquirt.

Looks good bro

Thank you KZfaq algorithm for poppin this up. And thank you Brew2l for this video I learned alot

Great video and content! Love the content that you provide - both you and Matt are great contributors to the Foxbody community/hobby!

I've learned a few things today about fuel injection. I've been told thing's n I c it was wrong lol. Very informative video..

Great video. Eye opener for me. I thought the calibrated mass it’s was the way to go for a mild setup. Thank!!!

KZfaq needs to make a love button damnit 😂😂, this info was is absolutely phenomenal. Now I know how to get the most out of my engine. Thank you Brew2l

Great info! I knew guys back in the 90’s who had some home ported E7‘s with B or E cams and explorer intakes who would crank the fuel pressure to make them preform more like a 21-24lb. Didn’t know there was a whole lot you could do with the stock speed density computers!

It also goes by how much power you have

New favorite video. More please.

This is a very informative video. Starting in 2005 when i boosted my car i ran it off a fmu with a trex in line pump and 240 intank. Theres no tuners close to where i live so i just lived with bucking, surging idle and stalling issues until 2012. I bought a tweecer rt and boy what a fun journey that was but i learned alot by reading and reading..as far as technical support, if you didnt have a sn95 ecu you were on your own. I fought this car for years, but after a couple maf sensors and learning more about what was happening i got it to drive and idle decent. I installed the terminator x in February of this year and what a difference. Welcome to this century. With all the datalog capabilities of this system i found out things about my car i would never learned with that old stuff. Plus having a built in 2step and a real rev limiter is a bonus. Yeah its 1200 dollars, but by the time you piss away most of your time chasing your tail, fighting gremlins this system can point right out if you know what youre looking for, in a matter of minutes. Theres preloaded injector info for dozens of injectors, even ford. I went from ford red top 30s to holley 48s and for the fun of it i started the car before changing the info in the tune and it started and idled like factory.. Try that with a a9 mass air set up. I always thought mass air was the ticket, but tuning on map is so much easier..just my opinion, its a whole new world now.

I have a turbo fox that needs a tune! Going to have to give matt a call! No one in west texas tunes foxbodies

Great video. My car has 30lb injectors, 70mm throttle body and a calibrated MAF. It runs food but if love to see what a tune would do for it. Unfortunately, no one around my area will tune the stock ECU

Say whaaaat? Loved the video need more thumbs up!!! When ya gona fix the torque boxes on the clone??? Just wondering, since there was like 3 call outs duringbthe live show's, dont wanna see the peoples fox twisted. Get that tune right and you'll be catching Andrew with ya c-4...keep doing your thang, tell Mrs brew2l and da folks south ga sends it's luv.

Excellent Q&A between Brew2l and Matt, discussing mods and tuning with MAF or Speed Density. Coming from the GM gen3 LS platform, SD is the predominant operating system with factory pcm or standalone 2+ bar forced induction applications. I've also experienced occasional hiccups with self tuned SD, under certain weather conditions when coming to a stop; however, the ability to do rolling burnouts makes it easy to live with!

Just go holley terminator X $1200 bucks for a full wire harness and ecu. Less wiring problems and an amazing platform that tons of people tune, and is self tuning on the fuel side. Just put a holley on mine

My buddy Eddie Miller owner of Engine Works built me a NA 347 with 42lb injectors and everyone laughed then I took it to Scoot Beers at Diablo in Florida and he thought it was way over kill but set a nice tune and was surprised how the engine loved that much fuel. I still have that old school Diablo chip designed for the factory ECU

Aah looks like my first foxbody is going to be at age 60, I’ve had everything else but was introduced to them, an was impressed with there structure, looking for one now, a roller so I can build it from scratch

You should check with all the tuners and see if they have a tune program that will work with any brand fuel injector cause some is different that’s why your friends car ran better with a factory ford injector 19 vs 30 the other brand.I learn that from Tony Gonyon at tuners inc.

Terminator X for me its been really awesome so far

Man you guys just opened my eyes and blow my 🤯 awesome

Fuel pressure will effect the slope of the injector. I am running mystery volvo bosch 30lbrs. I know what you mean about data on injectors being hard to find.

I bought Summit racing 42's and they had no injector data. It took me 2 years to get the car to run right and pass smog.

Great video, Pro-m precalibrated meters are different today. I will always claim the old school “pro flow” early pro-m had either better components or were flowed differently. example Up to 36lb injectors with a FMU on a supercharged fox was the go to and they would run great. Pro-M today with bigger injectors really need to be tuned.

I was originally very concerned when my tuner decided to put in 24 pound injectors after putting in a bigger cam and headers bigger exhaust pipes I also put in a intake from an 03 cobra with the bigger throttlebody. But after listening to this guy I realize that it may be the correct way and I really shouldn’t be worried. I’ve got a chip for it and I will be getting it dynode pretty soon but I’m just wondering how often will it have to be computer checked and dynode?

This video was very helpful. I have a pro m 75mm mass air meter on my 306 with 24# injectors. I want to swap out that combo and put it on my 331. My 331 has 30# injectors and mass air meter. Both have adj fuel pressure reg’s. Will the 24# setup be more beneficial for my 331setup with a custom tune? Both motors have heads, cams and intakes. Selling my 306, so I will be swapping out any necessary parts.

Awesome info i have a 95gt i have some ported gt40p heads getting ready to put them on i have full exhaust long tubes upgraded fuel system and all the bolt ons im considering putting 24lb injectors in it when the heads go on my question is should i upgrade my mass air or just stay with the factory size i do have a diablo chip in it now

Injectorsizing is all the new fat loss rage. I've been injectorsizing for 6 months and I've lost 5lb injectors.

I’m old school and still use the Anderson Ford pms. I tune it myself it’s very simple to use and i have 3 tunes on it. One for 93 octane that I only use after winter storage, one for the street with 100 octane and a final tune for the track with MS 103. I could get a Holley terminator x but I don’t think I need one yet. I have a built 347 with afr 220 heads and custom bullet cam, victor 5.0 intake, 1 7/8 headers and 3” exhaust. I currently have 36lb injectors but will be getting 42lb injectors in a week or two. My reason for a bigger injectors is duty cycle. The 36’s are at 97% duty cycle at WOT with a 12.2-12.5 afr with fuel pressure set at 40-42. I think my tune is pretty good the car runs in the high 10’s banging gears.

89 gt with gt 40 heads and intake, b 303 cam, headers and exhaust, ac delete also, should upgrade injectors and maf? Currently stock injectors and 65mm maf.

Great info , did he say you could run maf with the Microsquirt , cause I’m like you , car runs good one day then weather changes and it’s all over

Hey what website has the ford racing info you were talking about?

what mass air for a 1994 cobra

Do you know what size belt is needed for cobra pulleys and deleted smog pump for the retro fox?!?

hello from nevada, i got a new set of 30# injectors for a 347 mild build/daily driver. was thinking about a calibrated maf housing/sensor for the injectors,but now think im gonna keep my 70mm/ stock sensor and tune it. im a do it yourselfer so going withn a quarter horse to tune, thoughts?

What you foxbody guys prefer? LX front bumpers or GT?

Huge fan, so I have a question. I have a V3 Si charger, F303 cam, stock heads, 340lph fuel pump. I have a set of 42 lbs injectors and a 42lbs Pro-M meter. Do I put the 42lbs injectors on it, put the 42lbs MAF meter on it and get it tuned with my stock A9L or do I have to get a mega/microsquirt?

I’ve always questioned the whole calibrated MAF. It has been my experience that the cars with heavier mods usually are speed density anyway?

What do you need to get to tune the car though, I’ve got a 95 5,0 5 speed. It’s a larger cam, unknown origin, hits pretty good. Cold air, 3” exhaust with long tubes. That’s pretty much it. I’m wanting to do more, probably explorer heads and intake, later it’ll get a 351 out of a truck and I’m gonna go big on the heads and intake. Just wanting to know what I need to tune it now though, lol.

Question, I Got a 93 GT, with a 351w, Stroked to a 408, got AFR Aluminum heads,Long Tube Headers,Trick Flow upper and lower, 42 lbs Injectors ,Z 303 cam, but the question is I switched from 24 pound injectors to 42 pounds, had mass air calibrated, and it runs slower.i even changed the fuel pump to a 320 @ 40psi, fpm. Is it a fuel regulator problem?/ Timing?

My 94 TownCar 4.6L became almost undriveable. Nobody could fix it, just an egr code. Unplugged the MAF and it runs excellent but dropped about 5% mileage. Not sure what that means. I have not unplugged the 90 GT for a test.

OK so once you have it dynode how often does that need to be re-calibrated/dynode ?

How applicable is this to an 86 302 FI for an F-150, I want to do some bolt-ons so it can get out of it’s own way, not really wanting to dish out $700 to swap a computer and convert to mass air flow, I just wanna know what I can get out of the speed density system.

I have a fox body that I would love some help with it jerk sneezes and jumps it's been to the shop several times and they still don't put their finger on it and I think it might be a vacuum week

Hey sir I have a 91 F-150 that I'm planning very seriously on converting to a mustang computer I've done close to 6 months to a year worth of research physical research too as far as looking on mustangs and other f-150s also mine is a '91 F-150 before I got it they modified it great motor EGR delete header pipes true dual 1 O2 sensor i have 2 stang A9Ls lol I am extremely interested and wanting to install another O2 sensor installing the A9L and the conversion from map sensor to MAF pretty confident in doing all the wiring and everything but I'm curious what does speed density what is this I'm trying to figure this last little section out I'm a crafty person but I haven't come up with the lol lmao I haven't came up with the right word combination for the Almighty Oracle that is Google to figure out how to decipher this by self lol so if you could help with that it will be wonderful last question this is a truck it does not have the mustang heads nor intake so if I do install this all I'm not expecting a hundred horsepower jump lol but I'm looking for better fuel economy more efficiency everywhere performance everything later on I am going to look for some GT-40 heads and intake and install them you know do all the stuff not looking for a race car I just want to improve it to where it has some pep but not something that I'll probably regret because I'll keep on and on and on upgrading some of those not continuously if I keep going after this and it'll be trouble... JK I just want to have a real cool oddity and for bragging rights because people keep doubting that this could be done and saying that I can't do this 🤔🤔🤔🤦🤦🤦🤣🤣🤣🤣🤦🤦🤦 I've rewired and explore ECM and had to recheck because somebody else pulled the connector apart and then got scared and called me and I know I can do this I got it it's just a small things I really need to know for any input on the speed density police or help me lol

Any comments on Siemens or Bosch injectors?

Is leech motorsports the cats that tune neo cars?

your dyno tune is only as good as the person tuning it. pro m efi for the win. 19+ engine combinations. not one trip to a tuner. I drive my car, I dont tune it.

What’s up BREW2L big fan of your channel would like to send you pictures of my fox body do have an email address keep up the good work

This should help u matt lol.

Yeah until w.o.t with a boosted car and you pull a plug and you have detonation. You guys are only talking about idle. Talk to summit racing speed shop they will tell you what you need

Clearing your throat alot is a bad sign, get tested for corona virus

I will stick with my screwdriver. The Holley 850 hp series works perfectly.

Kinda janky to "jack the fuel pressure way way up".

Matt only talks money, not my fluent language
