But he doesn't have YOUR intake or YOUR cams or anything YOU did. So again, I don't think you "know" exactly where he shoul be shifting. You say yourself, once you build the car you put it on the dyno and then determine where the optimum shift point is. You haven done that for this guy with this car,have you? Also, looking at all these dyno reaults, SO MANY of these cars produce different power. So to say we should all shift at the same point is stupid.
