I know O2 voltage will go down if the sensor is heated up. Tune at night when it's cooler and let things cool down between runs. You'll get more consistant voltage.
.93v is perfectly fine on the 93 oct. My timing is getting pulled just a little, but I only have 91 octane.
It's really warm right now in CA too so I guess I'll lower the boost, mix in some 100 oct., or just run richer.
You could probably get away with .92v too. Shoot for it, watch the timing, and let us know.
