Hey guys i know people ask this alot but roughly where do you think i should be at as far as HP and E.T.. I have never ran the car before and it pushed 400rwhp with 21 psi on a mild tune. I know i need a new intercooler but looks like i don't have the funds to get one right now. So how much farther can i go with the stock intercooler. The 400 hp was before the ported intake, and with stock exhaust manifold. Sorry for all the questions but should i stick with stock exhaust manifold or ATR's with my combo.
