If you float the valves when accelerating before the limiter kicks in, something is not right (maybe the limiter has been removed by a tune?). I have NEVER hit the RPM limiter - just the speed limiter. The engine is making a LOT of racket before it hits the limiter, and the acceleration is dropping way off, so I don't see the need to try to hit it! I think the highest I've ever had it is about 5200.
