I think the ECU has a redline limiter at 6600 RPM. I had the same thing happen several times at the track yesterday.

fuel cutoff IS AT 6600, sometimes the needle is a little behind, but if its like a SEVERE cut of power, you hit the redline. if it just kinda felt slightly less strong, might be the natural shape of the power curve your feeling.
