Air Ratio

Im running on 7-9 psi turbo. My air fuel ratio is at 12.8. I meet some guys that r running 11.5 and said my car is running lean. What air fuel ratio should I be running to be safe?

Depends on the engine. Best way to find out is tuning. Turbo though is typically 11.5-12.3

Re: (badboypolar2)

Agreed, I was at 11:1, to rich. Right around 12 is ideal.

Re: (revhi)

So am i running lean? Should I drop it lower? how about 12.5? Or lower? I heard you loose power if its too low.

If you don't know for sure, throw your car on a dyno and have a competent tuner set your A/F ratio.
