I did the Cobb Access Port this weekend. My air fuel ratio is right above 10. My HR motor is with the JWT Dual Air intake and the Invidia Gemini cat back. I did pulls on a Dyno Dynamics Dyno. First pulls with stock map was 244. Stage 1 map netted 255, with air/fuel ratio bouncing between 11 and 12. Stage 2 map netted a pull of 262 with air/fuel ratio hovering just above 10. Is 10 too rich, and if not increased, what potential problems could I have down the road. Should I have the air fuel ratio be tweaked to 12 or 13? What's too lean?
Thanks for all or any input/responses.
"Perfect" is not possible, without potential damage to the motor. Given different climate and altitude. Also depending on how aggresive you want to be with + timing. Now there is ideal, to your vehicle. N/A takes well to 13.1 or so given timing/ knock is under control.
