??? about o2 readings...
I've been looking at my Autotap logs, and I'm wondering if I'm rich or lean.

My readings are 940-950 at WOT.

That's pretty rich. Figure high 800's, low 900's is where you want to be. A stock tune is rich, so if your PCM is stock, that's probably pretty normal.

If the wideband o2 on the dyno showed a 13.3-13.4, would that be an indicator that my o2s are going bad, or is that an acceptable difference?
