What are some typical good AFR's for cammed 3.8 on stock injectors?

GT2 numbers would be best.

I'll find out this weekend...lol it's jumping form 14.4 - 15.5 now, which Scott said was pretty good, that it wasn't to far out off place considering it was cammed.

For AF you want 14.7:1 during part throttle and around 13:1 when WOT
