I have a r331 with tea 205 tw heads and fcam. 10lbs of boost from masterpower76mm ptrim. car seems to just quit pulling about 5000rpm. not missing of anything just like it hits a wall. it actually seemed to run better with 302. Engine professionally assembled and cam is degreed in correctly. Is turbo choking motor?

P trim exhaust wheel is way too small.

I'd get another turbo. T4 BW 75/83 or even a Good ebay T4 with a large turbine wheel if your on a budget.
