Well my boost o meter tells me me I peg at 4200 rpm but I did the pressure to the intake maifold 20 psi and it could not hold up. It sounded like the thottle body was leaking so bad that my air compresser could not keep up. I have a 2 hp 4.5 at 90 air compresser but when hooked up to my intake leaked like a siv. My car idles well but I cant help but think Im having a problem with the idle air bypass valve or something? Anyone have this problem?
