I was wondering what the fuckin problem is! I have a full gsr setup with mods, and 1st threw 3rd gear, im unstopable, but 4th and 5th are fuckin weak! I think I top out at like 125! I was thinkin about gettin a fuel pressure regulator, vafc, and bigger injectors, (maybe spray), but thats only gunna help my acceleration.

What would I have to do to get better top end??? New tranny?
