The air/fuel ratio at stoichiometric (sp?), where all the fuel and air are equally spent is 14.65. As you gain more air, and it gets leaner, your number will go higher (more air).
As you go richer, the number will dip. Typicallay, folks aim for 12.1-12.5 at WOT throughout the RPM range.. that's a happy number to be at, while at partial throttle, the car will always try to be at 14.65 or just slightly leaner.
If the air/fuel drops below 10, the car will be blowing black smoke because it's running so rich.. and anything below 9:1, the car will barely run, so the numbers aren't quite so important that low.
