    Predator ???'s

    With the new update my truck doesn't seem to be as strong. WHY?
    Also my shift firmness is alot softer at part throttle and wot even with the ftvb and the firmness set at 80%. WHY?

    I have read Ryan's post and it was helpful but what about the other stuff in the update such as Torque Modulation, global shift pressures, etc. Any help would be greatly appreciated.

    yeah definitely do NOT mess with the shift firmness in the programmer, let the FTVB do it's job!
    Torque modulation is the computer cutting out 4 cylinders for a split sec during the 1-2 shift to be nice to the tranny.

    Torque modulation reduces power during a shift to make it easier on the tranny. If it feels worse throughout the range and all around weaker than it's not that.

    Globa shift pressure adds pressure everywhere, every shift point, every condition. In other words, you add 5%, it will add 5% everywhere.
