I powershift mine 1-2 and 2-3 at the track over 6000 and don't miss the shift and it shifts plenty quick.
I don't power shift into 5th either. Just comparing how my stock shifter was a little better than the MGW going into 5th.
yeah it sounds like you lifted off the throttle there darkfire. right foot should stay planted during a powershift. and grey diesel, i have the k member brace with torque limiters. but over certain RPMs its still impossible to get into gear. maybe motor mounts and stuff would help but trying to fix a problem and still be unhappy with the shifter it would suck.
