well I got around to enabling PS on my DHP. Well before I grounded pin 21 at WOT I was shifting around 5800 rpm, but since I grounded pin 21 I am shifting at 6000 rpm at WOT, maybe a little more. What I want to know is; is it ok for me to be shifting that high on a very lightly modded car, and is this overkill for my stock tranny?
