Lean conditions-no codes

Do you have the Alpina Trans Flash? If so, that could be the culprit due to excessive load between the rpms that you are having the hesitations. Or just need some tweaking on your current tune. Have you got any revisions on your current map? Or are you on the OTS map?

I don't have the alpina trans flash. We were using the Cobb ots stg 2+ map to make a custom map/tune when we found this issue. Adjusting fuel scalar, etc. wasn't changing the lean afr. So it's still running a Cobb ots map.
