I seem to have a tuning issue with my Power Commander with Autotune. The front cylinder seems to be running lean and the trim tabs on the PCV software are in the -20s and -30 around 2K-3K RPMs after I go for a quick ride. The rear cylinder is running good and there is very little change to the base map. Both cylinders are using the same base map numbers. I know one cylinder usually runs hotter, but for that much of change to happen? Plus the front cylinder is misfiring in that range and backfiring a lot. The bike runs goods below this range and idles fine. If I disconnect the autotuner, cylinder fires and bike runs. I checked the front header bolts and they are on tight. Any ideas would be greatly appreciated. It's not a mechanical issue. Seems to be a tuning AFR issue.
