"I also notice that some WOT testing was about afr 12.5-13.5 but some of them was more at 14-14.5 at the same run just a minute after the other between I floor it from cruise at highway."
Today I notice that maybe the difference is if I run uphill or on a flat straight.
I always testdrive when dialing in a carb on the same route on a non traffic highway and it's mostly flat but have an up and downhill as well, and when I run up the hill it's leaner than flat or downhill.
Am I overthinking again or is it so?
