Im actually shocked youre selling the testpipe with those AFR's.
Im saddened to say Ive been running it for a year now. I have a feeling my motor wont last 100k now.  |
13.7 to 13.9 AFR is pretty damn safe in my opinion, in fact you probably are making even better power than most of us if you are running an AFR close to that on a naturally aspirated motor. 12.0 A/F is something you might want if you are running a turbo or other F/I, but as you are only N/A even 13.9 A/F is pretty reasonable considering ideal combustion is 14.7.
Your motor is fine.
