hey i was wondering if any one knew the safest air/fuel ratio on a slightly modded 2002 mustang v6...my modds are..MAC cai, MAC LT headers, MAC H-pipe, MAC dual exhaust, Motoblue underdrive pullys(42%), gt posi rear end, and a diablo flash tunner. now i no i can change the air/fuel ratio with the tunner, but what ratio is safe??

The Great Cornholio

Without a Dyno I wouldn't recommend changing the A/F ratio to anything but 14.1:1 That is the optimal ratio.
