I have checked the AFRs 3 times on the dyno this season and posted much of the results on this thread. A few areas needed more fuel so I dropped the control pressure (a lot) in those RPM ranges. When the mixture seemed rich on the track, I slightly increased CP until I achieved peak performance.
The AFRs from the dyno are great at getting you in the ballpark, but I needed to do some fine tuning on the track. Since I don't have an AFR gauge in my car yet, this was the best method that I could come up with.
