I thought an air/fuel ratio of around 12.5:1 produced the most "safe" power for a forced induction engine while providing the least opportunity for knock? My car is lightly pinging at 15 psi and I've been told it's because my car is running so rich (like below 10:1 rich).

I ordered a wideband from Gadget today, so I'll know for sure in the near future. I'm planning on around 11.8:1 for a safety margin.
