Default O2 voltage on the spray

What are some O2 voltages from those who are logging while spraying? Mine seem too close to the NA WOT voltages. Like high 800's. This is just using a digital multimeter, butI don't think it's affecting the reading.

High 800's is OK. It think 875-900 is 12:1 area maybe.

But according to the chart that Dyno Tune uses for their A/F nitrous switch, high 800's is in the 13:1 range and my NA voltages are not much lower, like 850's.

But I don't know how much to trust the stock O2's.

You shouldn't trust stock O2's for WOT or N2O tuning. Get a wideband.

The stock o2 is good to let you know your in the ball park. .850 and up is ok if your not running tons of nitrous. you would want .900 and up if your using 150hp.
