idle you want to be about 14.7-15.2 or so, WOT you can be in the low 12's until 3500 or so then you might want to put it in the high 11's to be on the safe side from there till redline. Gives you a good safe tune that you dont have to worry about.

For your low throttle and crusing you can put your a/f's in the high 14's low 15's for the best gas mileage but just make sure when it goes into boost that it drops down where it needs to be.

Have fun.

you might wanna get those 13's into the low 12s high 11's. 13's will make you loose your motor!
