EVERY proper turbo system should have an intercooler! I tend to stick to proper solutions. I want to start with 7psi and eventually going up, I think that 10psi is not out of the question on a stock engine.
Stock engine is using a GM hotwire MAF, it actually works fine under boost, but I am going to use AEM FIC which uses a 3 bar MAP sensor, so it is more than enough.
