    Do you have transmission tuning. Might need to bump up the first gear torque limit.

    No, tcm still locked but was thinking it may be in trans. playing with virtual torque now to see if i can get car to react quicker. i increase torque in the 20g to 50g between 20-30 degrees timing by 45lbs to see what that does.

    If it’s the trans it will show up as Trans Tq management

    Yes, under tranny TM. First gear torque limit to 1000.

    Didn’t look at log, see what trans Tq management is doing in scanner...

    You can lie to Tq model on factory trans tunes, but I don’t recommend that, I recommend tuning the trans and reporting to the ECU and trans the Tq the engine is making
