i know you guys have said i can up the boost a little bit with and mbc, but for alot of boost ill need a chip since i have the 99. But how much boost could i run without a chip and just mbc?...even if it 2psi...i still want to know.

thank you

And as far as your sig, with the stock turbo I'd be asking that question, too. Where the hell is my boost?

 

Most you can run is 14psi with no chip, as for a mbc, bleed or combonation bleedw/ ball and spring mbc
