oxygen sensor voltage? dont know if this is the right place to post this but here goes..at what voltages is the afr roughly at? i have been tuning my car for quite a long time and under wot they jump to 940ish ,but keep in mind this is my setup in my sig. it always has kinda lost power up top but wasnt leaning out. well i got curious and lowered some of my maf tuning to lean it out a little and sure enough it totally woke it up. now back to the question at hand. i am now seeing 850ish on the o2 voltage and am just wondering what this is roughly equating to as in afr? and by the way i am absolutely getting no knock.

Narrow band O2 sensors can't be trusted for WOT. They are good for identifying stoich (14.7:1), which is usually ~500mV, and that's about it. First and foremost, I recommend investing in a WBO2.
With regards to your question, you could be running 13:1 at 850mV or you could be running 13.5:1. There's no consistency in the numbers, so nobody can tell ya for sure.
