I have the stocker/s475 compounds and can only get a max of 50 psi. I have read other threads of people with same set up hitting up to 70 psi. Just trying to figure out why I can't seem to get more out of it. I still have the stock tranny and TC and can hit redline pretty fast. A guy I work with thinks my weak TC isn't loading the engine enough to build boost. Is this possible you think?
