The 3.92 gears are hurting your mileage. I got the 3.21 set and I am getting around 24+ with the winter blend and 26+
with the summer mix. Best I saw was 28.5 mpg on a trip from Detroit to Mt Vernon IL.

A couple of notes:
You ran the Ethernet cable across the side Curtain Airbag.
Suggest that the "A" pillar be removed with a 10 mm Socket
