i assume these are WOT throttle readings. the stock 02's are not at all accurate at wot so i would not pay that much attention to them. but those readings are not lean anyways.

Yes, WOT readings. I know wide band is best but I have had some sucess reading my 02's on my Camaro. Maybe the values are different from Ford to Chevy. Hopefully I'm ok anyway.
