Just an update, the new engine is getting 20 city and 27 on the highway. I am averaging 22-23mpg now with no other changes (~18% improvement). I don't understand why it would be any different, but I'm glad to see mileage getting better instead of worse, lol.

This is a 2013 service replacement engine and Ford's latest calibration.
