Default 6psi to 8psi how much more power

How much more power should i gain from going from 6psi on a stock 2000 camaro with a sts standard kit to 8psi with manly valve springs zo6 intake and meth kit installed and boost turned up to 8psi? it dynod 440rwhp and 470rwhp before but power was dropping off at 5400 fast? just curious to see what you guys have to say before it gets dynod and finished.

with the right tune & meth, id think the extra 2psi would net you another 20-25rwhp or more. IMHO

You will be close to 500 at the wheels! I went from 521 rwhp @ 10 PSI to 587 rwhp@ 12-13psi with a pulley change only with my old set-up.
