sorry...i'm just anti a/f gauge at all, for 1 it's not accuracte unless it's wideband, 2 unless i have a way to log my readings i'd have to tune while driving cause i don't have a dyno in my garage, 3 even if i did have a way to pull up the ratios at the specific rpm ranges as soon as i tuned it out i'd take it out so i wouldn't see lights flickering every time i touched the throttle. i hate mounted a/f guages for the record
