Then you probably need to know how much cfm your turbo flows as well as the head your using and like volumetric efficiency crap that I understand nothing about, But I figure it has something to do with how much air is going to flow through your motor at 12 psi with your particular setup. Then you would probably divide that number by 12.5 and then you get how much fuel you’re going to need for 12 psi on your car.
But math does own me.
