the higher the number the more lean
the lower the more rich
at idle mind reads 14.8-15.2
if im just crusing it reads 14.5-14.8
at wide open throttle it reads 11.4-11.8
richer is better but too rich is bad.

The wide open throttle #s are what you need to watch and worry about!
If your seeing much over 12 or 13. Let off of it!!!!
My truck runs right on 11.5 at WOT.
I could go a little leaner but that's my safe street tune.
