I replied to your PM too...

Jerry knows what he is doing (he did my tunes), but a 10:1 or what looks like even worse in your case is just way too rich. Too rich is not conservative and can actually damage your motor. You should have your car reflashed until your AFRs are closer to 11.5 : 1 IMHO.

Generally tail pipe readings are more lean than if you were reading up close...So that means you are likely running even richer than the graph depicts.

Wow I never new torque shows you the AF ratio. What settings you use to make this work. I had the dials selected on my home screen but never shows a figure. On both my C32 and cls55. I would love to be able to see my AF as I drive along. Please tell how you got this to work. I have torque for Android paid app

If you still have cats, that will also affect tail pipe readings on the dyno. Just something else to think about.
