A/f ?
What is a good air fuel ratio for our engines? Would 13 to 1 be ok? Should it be leaner at the lower rpm's and richer(fatter) at 5k and up? I'm trying to figure out what is best between the most HP and the safest A/F ratio. thanks Jeff

I'm no tuner but when I dynoed my 01 L, the a/f sensor showed an average of 12.4 to 1. At that time, I had a JDM chip, oil breather, JL filter, and Mark's throttle body. It was hot--July, in South GA.
