Don't go over 11psi without a cooler, the EGT's will get too high, and it goes without saying that you'll want an EGT and boost gauge before you do anything. And at 11psi you won't need to stuff around with fuel settings unless you want to. (Not recommended unless you have a cooler)
Plug the spot where the relief valve goes with a brass fitting, as the relief valve will open at 7-8psi.

They normally don't go great off boost, not a lot of power but it should still make good torque before it boosts up. Have any fuel settings been adjusted?
