Is this for a blown car? If it is you need to run it richer. 14.7 is for good gas mileage and good emissions. If I remember correctly in a NA its somewhere in the 13's.

13.2 will be perfect for a non supercharged vehicle, if you are going to run high speed for a long time say a few miles at WOT set it to 12.6.

Thank You

I haven't really figured out exactly what that will do yet, sorry. I think sniper will put you really close to you optimum air fuel ratio if you put your mods in. For reference for others I have read that a turbo car should have a 11.2-11.8 AFR. I'm not sure though.
