4 Grand in Park, don't you like your engine, it sounds like the rev limiter is kicking in. It is not designed to have high no load engine speeds.

I agree. I researched the subject, and found that the rev limiter is set at 4050 rpm.

The rev limiter is set at 4000 rpm in park for the Grand Prix. Its a safety so then you don't blow you're engine in park.
