Forgive my ignorance, I'm looking at buying an Aeroforce interceptor guage to monitor air/fuel, does anyone know what your air/fuel ratio should be for an acceptable range on a 2011 mustang Gt with a Roush TVS using premium 93 octane fuel? I have a canned tune and haven't had it dynoed yet. I know, its probably a good question for a tuner. I would like to know what the acceptable limits are for cruise, idle & wide open full throttle to make this guage usable instead of looking at random numbers with no meaning. My car runs fine and I want to keep it that way. I'm sure this info would be helpful to others as well.
