I have an S13 SR20det Blacktop and a walboro 255, and stock injectors. I sometomes cranck up the boost to 13 psi and dont know if its really safe? I have the Apex 550s and a z32 maf but did not install them cause gas is 2.50/ GAL. When i crank it up, my Greddy EGT gauge doesnt really go up that high on boost, but i still want to be safe. Is it ok to up the boost that high on a stock motor with a FMIC and stock injectors?
