Anybody ever adjust there Air to Fuel ratio on that thing. If you have tell me about it. And anyone know a good number to go for for a naturally aspirated stang. I heard 12.9 but i thought that was kinda lean. HELP PLEASE!

I thnk I read somewhere that it was 13.9 or something, but regardless, unless you are on a dyno, or have another means to get a really accurate a/f mixture, don't touch it :-p I HAVE played with it, and I set it back to original :-p

Just beware though, if you install long tube headers, a good CAI, and a plenum and TB your Air/Fuel will drop down into the 11's. It would be a very good idea to bump it up a little until you can tune it on the dyno because you will burn up valves and valve seals if you leave it that low.

12.8-13.2 try to tune it for 13.0 its a safe tune
