Learning how to scale 0411 Gen 3 LS ECMs for BOOST! 

Didn’t know about you until the Cleetus video. Learning more useful info here than in the Tuner School books and other youtube tuning channels combined.

Matt, get ready for a RU-vid tune-up brother! Cleetus sent me and I'm ready to learn brother. 🤠

here to watch the channel blow up.. congrats.. great job on the GMC ..

Man I needed this 2 years ago lol

So much info in this video. Very helpful . Thanks Matt.

dude, i would totally pay for the data from the website, it would be so awesome

This video just answered so many questions that I had about using an OEM ECU in an upcoming project, in order to keep it as cheap and simple as possible, yet retain a bit of flexibility in terms of boost control depending on the situation without having to change complete ecu maps. From your explanation, what I gather is that it will allow me simply toggle between between 2 or 3 preset boost levels on a seperate controller on the fly (ie. Valet Mode, Normal, Towing/Hauling or whatever). Again, not a race vehicle by any means, but giving me the ability to have something like an 6psi, 10psi and 14psi preset to choose from on a seperate controller. I gotta watch more of your videos now.

I love your intro with all those revving motors. Makes my heart sing

Good job on the GMC fella 👏🤟

Great video man, im forsure going to buy and HPtuner. Hope have you remote in and get me going. Keep up the good work

Great info as always, man. Keep them rolling! 🫡

Matt, theres a ton of great info in this video. Thank you

Great info as always 👍

Great video man. Great content as always.

Been waiting a long time for this! lol thank you!

Thanks for this video. I'm working on this next.

thanks Cletus awesome content Matt!! 👍🏻👍🏻

Love the info. Wanting to build turbo 5.3 yukon xl 4x4. Your teaching makes it easy for me to learn the skill of tuning

Great information! Learned a ton. Thinking about doing a turbo on my stock Gen 4 5.3L. Would be awesome to see the same info on a Gen 4. 🤙🏽

Awesome information. I can do LS swaps, but I don’t do tuning, it’s great that you can do remote tuning. I will be contacting you soon. 👍🏼

Here from cleets giveaway video.. Goodluck on growing your channel your about to blow up..

Cleetus sent me, I'm here to stay brother!🫡🫡🇺🇸🇺🇸🇺🇸

Very nice. I'm planning to put together a 370 with LSA supercharger and need to start on the tuning part. Going in an 01 Sierra

Hi MAT.I watch your videos a lot, they are very cool. Thank you so much for your hard work! I'm cleaning my turbocharged truck. What happens if I just specify the size of the 75Lb injector and don't scale the tables? 👋👋👋👋

Cleetus sent me:) 🤘

Currently dealing with a “tuned” c5 corvette with a Magnuson supercharger kit. Maf only tune, stock map sensor, 42lb injectors but still the stock injector data except they did change flow rate. Really a pain in the ass starting with someone else’s tune which seems kinda wonky.

Hey Matt, I think I’ve found your channel just in time. I’ve got a 2008 gmc Sierra 6.2L on a 6L80, do you have any videos about tuning something like that? And will you help me tune mine? Your vids are bada*s and you’re a beast tuner dude, thanks in advance!

How much do you charge for tunes?

Hi, I have a question on the power enrichment. I saw at the commanded KPA you went above 1.0 for the EQ. Aren't it supposed to be lower than 1 Lambda? To run richer? Exp 0.8-0.85? Also note I am om the Audi platform with HP tuners Still a noob here busy learning lol

I mean yeah i can understand this .. mine is po1 tho .. my spark table is almost maxed out on a mild built 6.0 also maf peaks at 11k so adding a turbo everything will be way out of range

Maybe I missed it but do you need to halve the Cylinder Volume under First General tab too?

Is there any way to tell if your tune has already been scaled? I’m tuning off an existing tune that is already a 3 bar os but I changed the injectors and injector data. It was tuned by someone else before.

I went to the tuning website and I’m not seeing anything for a gen 3 forced induction base tune. Is that not available or am I just looking at it wrong? The vehicle I input was a 2005 gmc Yukon xl 5.3.

Would you recommend draw through maf on Gen 4 also?

You ever had a E38 pcm that didnt have a 2 bar OS option?

So 412 injectors ? On this demo ?

What are the best ways to learn tuning? Are there courses at auto tech schools? Good online courses?
