    Look under the engine torque tables inside the engine calibration portion. They all pertain to how much torque the ECM tries to theoretically limit the engine to.

    Torque limited injection quantity is one to play around with a bit.

    Careful with the TLIQ table. It controls max fueling as well as how much it defuels on shifts. If you go to big it wiull not defuel at all and even fully built trans cn come unglued running without defuel. It is the table though that has the most control over max defueling, and is teh table referenced teh most for how much fuel to give for a defuel request.

    It all depends upon what your after. You just basically start making changes until you find where you need them changed at.
