    Not currently, gm changed pcm's for 2011, we are working on them now.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Not good gm put a few pitfalls to work that I'm not sure if we'll be able to find a workaround for.

    Hey Bill any updates on 2011 tuning capability?

    Looks like BullyDog has some prototypes out in the field being tested as I type this. I have no idea how their device interfaces with the vehicle, but Im hoping HPT can figure something out soon!

    Would be great to see HPT beat EFI to the punch on this one! Great way to sell a bunch of new software too. Duramax/Allison market is big and growing.

    No, theres a reason why EFI hasn't hit the market, same reason we haven't. GM made it very difficult to read these pcm's.

    If they're doing them, they don't have anything available.

    We have a 2011 3500 at my work and it gave a code yesterday with 400 miles. P0299 turbo under boost. They said it was in the programing from the factory. So they retuned it and it has a little more power. Still not impressed with this years model. Need tune bad!!!!

    No ETA at this point, everyone offering custom software is having a hard time with these pcm's unfortunately.

    Why does GM make it so hard to access the computer? And why are Bosch's complete bitches and why are delphi's easy? Curiosity will kill me one day...

    More than likely if it remains stock tuning they have less warranty claims to deal with I would say. I would say many repairs have been done for those that have over powered the drivetrain, return it to stock, and got it fix for free.

    That makes sense.... But isn't it pretty much impossible to put an LMM back to stock without GM knowing calibrations were made to the ECM?
    Why not just continue with that and leave us with the tuning capabilities and the added performance and winnings at truck pulls and drag strips?

    Maybe if every other "workaround" question wasn't "can I swap in a different pcm and tune on that one and then just swap my old pcm back in for warranty work" GM wouldn't care but since thats not the case if I were GM I'd try to protect ourselves as best we could in any way we could.
