Still 35-38 hwy on 93 octane, higher side with non alky gas on Mountune MP-215 at 75 mph. Has been consistent for 7 years for me, just keep you foot under control when cruising. At my age I am no longer using the accelerator as an on/off switch, I know what Fi-Fi can do. Curvy back roads are her element. Just set the cruise on the interstate and crank up the music with '60's/'70's rock.
Mustang plug...this year we took my wifes '19 Mustang GT/CS with Coyote and the B&O CD sound system. Between the variable exhaust and Stereo the car makes glorious noises and 8000 mile road trip was a ball! Usually take Fi-Fi but back pain issues demanded the better ride this year. BTW hwy mileage was about 27-28 mpg @ 75 mph in the Sport mode so could have done better. Again, keep your foot out of it for mileage.
