How much hp could I expect from this combo?

Assume it is tuned to perfection and if I didn't mention a part, it's probably stock. My goal with this engine is to be as powerful and responsive as possible.

How much boost could I run with the slightly higher compression pistons? I'm considering the 9:1 pistons to get a little more power and make the turbo spool faster.
