Let me see what I can help you with. I don't know the stock compression ratio...therefor I can't help you with the boost level. If I were you, i would throw some new pistons in there. Drop me an email and I will get you some pistons.

The other option with the pistons is to take them to calculate how much metal you would have to take off to change the compression ratio and make sure that you have enough to do it.
How much power are you looking for?
