Ok I should ask what the optimal air fuel ratio should be while in accel enrich? Or is that engine dependent? Iím currently running 1bar with code59 on a quad 4 2.3l. I have all the stuff to super charge except time to install so if you donít mind including 1bar and boost AE AFRís I would be great full. From what I have read 12.5-13.2 AFR is PE, but must have over looked AE somewhere. Feel free to correct or criticize :-) Thank you for any help!!!
