Tomorrow when you go see your tuner, try to get a dyno graph with AFR readout. Then, compare those numbers to the numbers you're getting from your logger to get an idea of the offset between your data and the dyno's wideband...at least until you get a standalone AFR gauge...if you're concerned about it.
Also, since you are running 93 octane, you can actually run a little leaner than you would on 91.
