Whats the leanest you would go?
I was wondering what o2 sensor voltage you all have tuned to. I understand that a wideband is the best way to tune air fuel, but what is the leanest you would go on the o2 sensor voltage? .88? .86? .84? Let me know

To be safe with a turbo-charged rotary, the maximum A/F at WOT should be about 12. I'm not sure about the 02 voltage, but I believe many people use a value of 0.85 at WOT.

It is really pushing it to tune your car based on the stock O2 sensor. Get a wideband or you will join those that have dumped their engines using useless information from the stock O2.
With the stock twins and no more than 14 psi, I would target 11.7 AFR.

I think if you get behind your car and smell your exhaust, you'll have a more accurate idea of what a/f you're running than using a stock o2 a/f gauge. DO NOT try to tune with a stock o2, like mmaragos said.
