For all of you who have turboed your gts what psi are you running and what internal mods have you done if any?

sorry to say not many are turboed, and even less with internals. Hard to believe I think I am the first GT that posted independent turbo dyno result, many claim that they are turboed yet they do not show proof. I am going to do internals maybe 9:1 compression for my GT maybe can run more boost with that, trying to get to higher psi get more HP.
