I never touch my fuel and air, you are only going to get so much out of the predator and its not huge gains.

Stock car with a predator will not run lean. I imagine the car ran some where around a 12 for A/F. A Bolt on NA stang can handle a 13-13.5 ratio with a proper tune.

I strongly recommend getting on a dyno before you start playing with the A/F for WOT. You can do a lot of damage if you don't know what to listen for or what you are doing.

I have to get a custom tune because my car goes very lean at tip in and levels out after 4k, and is still rich at that end. I plan on getting a custom tune to fix the lean tip in and lean the car out a bit.
