Re: ideal a/f reading?
There is no perfect afr for all cars, every car is different. If your on a dyno you can see what the car likes. For a street tune most aim for 14.7 at idle and part throttle some cars like a little richer some can run a little leaner. Wot can be from 11.5 - 12.5 depending on the setup. Most of the time I do my street tunes at 11.8 if im on a dyno ill see if it makes more power if I lean it out.
