Not much info to go on, mate. Does it build boost on part throttle after 5Krpm ? what about on part throttle ? You might wanna check the piping for leaks first. After that would be vacuum lines.

I would check and see if the fins are hitting the housing itself. There is a possiblity that your turbo is not balanced. Does your exhaust smoke allot when driving?

once the boost dies, i can let off and build it again. I can part throttle it all the way to red line. I'll cheak for leaks? wouldn't I have idling problems?
