Stealth ES will not pull through to 7k

The car seems to start to faulter around 6k RPM. It will not continue to pull.

Any idea's?

Could be a million things with your kind of detail giving. ;) How about you tell us the situation surrounding the problem?

Are you getting any Check Engine Lights...how many miles do you have? When is the last time you did any maintainence or tuneup? We need alot more info.

Using 90 octane fuel...alcohol blend... <---not sure if thats a no no or not.
234k on the engine.
Doing a cam seal this weekend and possibly the timing change etc.

KnN filter on it.
Ractive exhaust.

Is there a reason you're using 90 octane fuel? and not 93?

Yup, I am cheap.

Its $1.04 a liter here.
