Won't Rev out

[WITHERS]

I have a 09 M6 with the CPC stage 2 kit. I had some fueling issues and with the great advice I got here it seems to be running alot better. The throttle response is great now till about 7000 rpm then it just stays there. I'm riding at about 2500' at the bro's farm,just long flat pulls in about 2' of fresh. If I take it out on the road it will hit 7900 rpm and pulls hard. Any ideas what it could be?????

I havent changed the clutching and it would rev out before. All I did was pull some fuel and 1lb of fuel pressure. This affects clutching that much??????

Try playing with your clutch weights or bring your fuel back to where it was before. Did your AFR/EGT numbers change much also?

What kind of egt/AF reading are you getting when your at 7000rpm. I would say clutching, or put a new belt on it. How many miles and what is the current clutch setup. Try a new belt first.

You'll notice the question mark at the end of the sentence. That make's it a question, not a comment. Get an education.
