AFR with NA combo

madramper · 09-25-2008, 10:31 AM

I have done tuning on a supercharged application where the AFR is supposed to be in the 12.0 range. What about on an NA setup. Should it be leaver than that? Same range? What is ideal.

12.5-12.8 na is the target chip.

Chip,

If memory serves me correct a Perfect A/F for N/A is 13.5. I have always run my 95 (when it ran) the A/F i always tuned for was 13.25 to 13.3 when running N/A
