perfect air-fuel ratio???

hello there.Does anyone know wich is the perfect air fuel ratio (i mean the best combination of safety and power)for my jackson racing supercharged integra type r with stock pistons and rods.the boost is about 7,5psi.After tuning i see at my aem gauge 12:1 until 4500rpm and 11,5:1 after 4500 rpm.I think it is extremely safe...With this air fuel ratio it performed 250whp.thanks

For what you have done to the car, I think that AFR is spot on.

Extremely safe might be going a little far. Especially non intercooled. 0.75 would be extremely safe. Being it's non intercooled I would keep it around 0.79 from 4lbs up
