Hey! Brand new here. I live in Waukesha, about 20 miles West of Milwaukee. I've got a 2005 Mustang GT that I've done some work to here and there (CAI, headers, underdrive pulley, new hood...). It's been frustrating me cuz it's gas milage seems to be dropping despite driving conservatively and putting parts on that are theoretically supposed to help MPG.
Anyone else here in the area?
