650cc with evo8 maf

[Thirdspazz]

OK I have the evo8 maf and 650cc injector with a ecu chip to match, But the fuel psi on the computer is 37psi and i have a 255hp fuel pump do I still have to turn up the psi, or will 37 psi be ok, P>S and a had the phantom knock removed on the ecu, but I have knock in 5th gear in vac on highway,,

Do you have an AFPR? And do you have a method to log knock? Sounds like it could be leaning out under light load conditions, it may not be as noticeable but you probably have some knock in other girls when you're not under boost
