The a/f ratio you see in AutoTap is the -commanded- air fuel ratio. There's absolutely no guarantee that is what the motor is actually running. If your engine is entirely stock, then the commanded a/f ratio shown by the PCM will be reasonably close to actual, but any modifications will skew the true value from the one being returned from a table in the PCM.
In order to accurately determine your true a/f ratio, you'll need a wideband O2 sensor.
