Once I figured that side out on the dyno, then I worked on the tcm shifting pressures as well as how much tq reduction was used for shifts. When finished it drove like stock under normal conditions, and then when hard in the throttle shifting became very firm and quick. I had some others drive it as well and they loved it so I'm going to implement it into one I'm working on now to see how if I can replicate the results on a different setup. Thanks for the advice, good to hear someone else came up with the same approach and has had success with it as well.
