Re: Help with air fuel ratios?
for NA you can run up to arround 13.5:1 safely, AFR's below 12.5:1 are usualy reserved for blown/turbo cars (or mine lol).
You could lean it out a touch, but your AFR's are reasonable and dont show the typical falcon trait for running at 10.5:1 (like mine and 1/2 of SA's cars as shown at DD3) under WOT. Clearly this is from a good macthing cam (DEV4) to your stock fuel maps
Ive been described as a vault of usless random knowledge.
Ill take it as a complement i think.............
