What is the best A/F at WOT...getting 13-12

[CHRGEIT]

Took the truck out for a ride tonight on a beer run and at WOT it was reading 13 then dropped to 12 at WOT. I thought 10 to 11 was the best A/F. Not sure what these motors should run at WOT for A/F. No check engine light was on at the time.

12.8 WOT for non-FI. So you are looking good.

10-11 is pretty rich

12.5 WOT is perfect, higher is leaner, lower is richer and safer and around 14.7 at idle.
