Go into the shift time tables and turn them down. Its all in preference but I wouldn't want to run perf. On all the time one of the great things about having the performance shift button with serperate tables for most of the trans settings is being able to have stockish tables on normal shift and really aggressive tables on performance shift. Another setting I have after scorching a set of raybestos 4th clutches is 4th up shift at 255mph over 90% tps so it never goes into 4th at WOT. It will set solid on the rev limiter in 3rd no matter what until you let off. I also have high mph values on the manual 1 and 2 detents to get the car back down into 1st or 2nd at higher rpm for roll racing.
