At idle or 2000 rpms? The E91 numbers look fine, about where mine are. +1 E92 is low on refrigerant.
A scan tool like INPA can give you evaporator temp. 36-41F is about where evap core should be. And in hot S. FL, a 35F temp drop at the vents looks ok. You can try with windows closed and parked in the shade, and see if vents drop lower after 5-10 minutes.
