Yeah what ND4SPD said,if you want to make power up top your going to have to get at least some cams.When I had the FM reflash my car fell on its face after 6250 because I was on all stock internals.No cams or head work being the reason it fell on its face,but IMO you dont need to rev the car out the high anyways.Just my opinion.
