not sure ### the problem is. car does not leak boost. the timing belt is on right, plus the light reads right on 5 before. the car runs great all the way up to 4500 rpm, and like in first if it spins them it revs out to 7000 rpm. if it dont it falls out at 4500 like every other gear.

Is the car misfiring? Maybe you are reaching fuel cut. What kind of boost are you running? You need to try to explain your problem better if at all possible.

P.S. What made you put this in the NorCal Region DSM forum.

Please limit your tech questions to the tech forums, not the regional section. Thread moved.

Also, please work on your capitalization and overall grammar.

One thing you should check for would be a Pre-Turbo exhaust leak. Those can cause havoc on your performance.
