big t28 with pump gas, how much boost...

[kdrkmstp]

I'm going to be getting my car tuned on thursday.
Right now I have the big t-28 with walboro 190, rc 550, and s-afc.
evo3 o2 housing, rre dp, rre test pipe, n1 catback, and other basic upgrades. How much boost could I push up to with pump gas???

well i dont know what octane your gonna be using...lets say 93 i would say 18psi until you get a FMIC then you can probably push it to 22psi with proper tuning
