Actually, now that I think about it, since you're running an FD engine, it may not really overboost too badly. They ran 10 psi stock (when you can make the twins behave), and plenty of people ran them harder than that. I wouldn't expect that life will be good for the turbo if you try to maintain 10 psi to any significant altitude though.
