    Duramax HighPerformance Idler Kit is now available!!!

    Ok, we finally have these ready for market to take care of the issue once and for all without adding any undue stress to the crank and belt stuff. Not sure why it took me so long to figure it out but we have it now! This uses the factory or aftermarket belt routing for dual fueler setups so...

    Actually yes sir, #10 Buddy Callaway is a stock motor/stock turbo LB7 truck! Pretty wild what you can do with a stock motor these days that we all said wasn't possible 5 years ago!

    serpentine belt comes off

    Well, after fighting the issues not only on my personal trucks and on the engine dyno for many years It dawned on me that we were going about it all wrong(myself included). I have been working on this for a while now and I haven't thrown a belt with this setup and it doesn't add any extra...

    Anyone ever use a dragy?

    Yes sir, it is a really small world! Wyatt Stengel, the main mechanic/fabricator for boosted boyz is a buddy of mine and I'm helping him on his drag truck project. Super down to earth guys that figured out how to get paid for doing cool shit with their friends! Brett and Clay have been...

    Anyone ever use a dragy?

    Lol, but you are still watching them aren't ya? It is just the new age tool compared to what we used back in the day, the G-tech which was damn accurate as well 18-20 years ago lol. Just like any accelerometer, if you slip the tires much it doesn't see it and there for the numbers are off...

    Is this Normal?

    01-02 tcm file is the king because it just doesn't give two shits! It knows its job and it does it the best!

    Is this Normal?

    Not that I know of, more like an algorithm in the background same as the timer for the lockup delay and down shifts.

    Is this Normal?

    It isn't in the file that we can see with EFILive if that is what you are asking.

    Fiberglass Panels

    No sir, track only! I have glass frontend and doors and bedside on my proMod and I wouldn't even remotely think about using that stuff on the street.

    Rail pressure climbs while coasting.

    Regulator control isn't open enough on the bottom, downside is a pressure drop at times if you get it fixed for the rise while decel it can create an issue in a different spot.

    Banks DataMonster or Edge CTS2

    I can tell you not very many at all! That's why I moved mine to my wife's 08LMM because it had more data displayed. I don't like the fact that some of the important pids the data isn't correct either like map sensor.

    Tow/Haul mode not coming on

    The connector for the shifter itself is less than 6" from the shifter so you need to unplug it and ohm the wires to see if they make connection/close the circuit when you push the button. Very common for the wires to break where they come out of the shifter lever causing the issue so you just...
