With running 32 inch tires, 3:55 gear ratio and Boss 6.2... 16 MPG highway is actually pretty decent IMO

I use Forscan and a vLinker FS adapter that connects to obd2 port. They recommend another one also (OBDlink EX) but it cannot talk on 18V pin 13 which is required for changing those types of settings (axle ratio, tire sizes,,etc...) I have been using vLinker FS to update many modules with Ford's current calibrations, since I had not updated any firmwares since buying the car in 2012. For example, the IPC module has an update that fixes the "can't reset oil life" after 60k on odometer issue.
Take several days and read thru forscan forum. They basically help u thru each step.
