What's the best Air/fuel ratio to shoot for on H22A motor?

What's the best Air/fuel ratio to shoot for on stock H22A motor?
If using the lambda scale should I shoot for 12.5:1 or go for 13.2:1?
If using O2 sensor volts should I shoot for 0.75 volts - 0.88 volts?
What have you guys gotten the most HP/torque from? Have you confirmed this on the dyno?

please tell me you're not using one of those vafc things to tune the fuel.........
Ever engine is different - so, you have to get it dyno tuned if you want the best results - period.

the best for each engine is different....you really need a dyno or something that will allow you to measure differences in power to see what your engine likes.
