ok here is the problem whether rolling or from a stop the car maked this awful rattling sound when it reaches 4000 rpm
I have spoke with a friend of mine and he informed me that he thinks its hitting the rev limiter( maybe the throttle position needs to be adjusted)if anyone has had o heard of the problem any advice would be great thanks

It's not hitting the rev limiter at 4K. If I remember correctly the stock limiter is set at 5400. You have somthing else going on.
