    Regardless of MAF, SD or blended, This should represent closely to the power the engine is making

    That's what I thought, my truck is easily making over 700 at the crank and the virtual torque is stock.

    Some VT tq tables are much closer then others. How much engine tq are you making in the scanner?

    I'll have to look at log but I'm pretty sure it's maxing out low. Can't go wot yet, trans got to be completely retuned now that it's built.

    The engine torque PID pegs out early. Use trans engine torque, that pegs out way higher.

    How much more pressure (or less) does a built 6l80/90 need compared to a stock one? Or is there not much difference at all as long as the torque models are correct?
