It's amazing how much humidity affects the AFR.
On the left is a prior run, on the right is from today, Both were hot sunny days, although today was a little bit more humid.
All fuel settings at 0%
4000 13.6 12.2
4250 13.4 11.9
4500 13.4 11.9
4750 13.3 11.7
5000 13.1 11.5
5250 12.9 11.4
5500 12.7 11.0
5750 12.3 10.7
6000 11.6 10.4
6250 11.3 10.2
6500 11.3 10.2
Back to back runs are always withing .1-.2 of each other throughout the RPM range, so I trust the accuracy of the Wideband.
But the AFR varies a huge amount depending on the weather conditions. I guess I will have to retune it to 12.7-13.0, EVERY DAY lol

The second row was pretty much what I got when I was with some bolt ons. From my experience the Tib likes AFR ~ 12.5. 13+ I lost a lot of horses
