John,
Is yours a 4 speed or auto?
I am assuming that the 4 speeders can be setup a bit leaner in N than the auto guys due to the idle in D issue. Another variable is the outside temps. I am assuming that in the Summer, I can probably get into the 14's. But right now our temps are in the 40-50 range so I am running mid to high 13's on warmup.

What kind of A/F ratio from a stop (steady accel) ?

Thanks!!
