    dumb question!

    Guys:D, I'll like to know how much can i boost my car safely. Here's the deal, the mods that i got: Ex. manifold, full exhaust, fmic, 550cc inj and walbro fuel pump. I have the standard ECU and it's running pig rich atm... you guys think i can go to around 13 or 14 psi without a tune? Maybe...
