2015+ Mustang gt transient fuel questions.

[sbush265]

Since I've started messing with tuning my car I see my afr running rich when clutching in and coming to a stop. Once stop the fuel trims even back out to close to where they should be. Should I be looking at the transient fuel tables or is there another culprit?

Car: 2015 mustang gt, manual

Mods:
Long tubes and pmas cai.

Current tune file
