A general rule-of-thumb is between 5 and 10 horsepower per PSI of boost. The more mods, the higher up the scale. So at worst, 8PSI ought to be worth about 40HP, give-or-take. Add an intercooler, even more go goo. Big Grin

What he said. (Is this considering post whoring? I don't meant to, just can't help it...)

Adjust slowly, and watch your fuel somehow if you can. There, I added something useful.
