you can get away with boosting about 7-8psi with stock pump.any higher..pump cant keep up with fuel demand..leaning the motor out and possibly blowing the engine

Hmm, I wouldn't if I were you. I was boosting for a while, not knowing that my inline pump wasn't on. My EGT temps were way high, indicating a pretty lean mixture. It was around 1450F or so.

Tomakit from HT helped me out with that, and now the temps hover around 1200F even boosting like a madman.

Incidentally, Tom pulled my plugs for a compression test and noticed piston shavings on it....probably from my boosting without the proper fuel.
