Guys I have something wierd going on here. My car doesn't want to leave hard and it doesn't pull in the upper rpm's. It won't leave hard because it is a nitrous converter, and it doesn't want to pull up top. The lack of upper rpm acceleration is what puzzles me. Is the tranny slipping? The car does not want to move from 5000rpm up. This is sucks because the motor is a 370 ci with RHS/ETP 225 heads a 239/250 cam and fast 90/90 setup. What should I do first?
