What are our front 02s suppose to read?

I have logged my front two 02's. I read a few high .7's mV's but mostly low .8's. With my Camaro the best performance is around .89-.90.

Do I have a lean problem? This is a tune from Evolution.

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.
