When tuning for a target A/F ratio, there are many factors that come into play. Until you have enough data to make an educated decision regarding the A/F ratio, a safe guess is about 12:1.</TD></TR></TABLE>

Even the CTR piston LS/vtec with Blox blah blah cams and portwork with a 2 layer gasket saw 13.0 AFRs on 93 octane at lowest. 12.0 is a good guideline for BOOSTED cars - you'll just lose power if you tune that low on a NA car.</TD></TR></TABLE>

I quote from: http://www.phearable.net/tech/....html

"For example, in most cases forced induction motors require a richer air fuel mixture of 12 parts fuel to 1 part air at wide open throttle using pump gas. Where as naturally aspirated motors usually run 13 parts fuel to 1 part air at wide open throttle."
