    2011 chevy impala 3.5l

    Trying to figure out the best tune for my son's bump and run race car. Running e85, removed cat so far. It's a short track so he usually keeps it in 1st so it slows down when he let's off in turns. Need most torque on take off to push cars.

    Likely not much you can do. It's a V6 that likes to rev and doesn't have much torque down low.

    If the computer knows it's running E85, that is a good thing. Then just optimize the power enrichment and air fuel ratio settings at full throttle for using E85.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Turn pressure up. Turn of torque limits.

    If it's staying first doing anything with shift pressure won't do anything. You'd increase shift pressure if you wanted it to shift firmer/faster to a point.

    1st gear really has no limits if there is no traction control or working ABS system. If you turn off all of the abuse settings if there are any, it could harm the transmission in the long run.

    If you don't post the tune we can't help you with anything, kinda need to see what you are working with.
