I believe you get 4 to 5 hp from shimming the waiste gate but again that is all hear say.

Going to 3 inch exhaust all the way around will give you some nice top end. It shouldn't mess with your lower end torque too much sinse you're a GTE.

I would guess the exhaust swap would give you an additional 10 hp. But I am sure someone will correct me sinse I am ball park guessing. I think those are pretty safe or "close" estimates.
