As far as boost goes, I run 14psi daily using 550s and an AFC and im still running rich. Pat runs about the same psi on stock fuel injectors and no fuel controlers. Bumping your system to 15psi using the basic map settings on Road Race Engineerings website in conjunction with an aftermarket pump, everything should be straight.


One more thing, if you need injectors I have some 550s im getting rid of. just PM me if interested
