One way is by posting the new tune file using HPTuners and I could compare with the OEM tune file I have. I am curious also.

My guess is that they leaned out A/F ratio at wide open throttle. My stock file commanded 11.25 to 11.75 A/F ratio at WOT.

Id say it had nothing to do with the new cal, and more to do with the fact that the cats were clogged

If anything the new cal likely addresses COT protection, etc.
