Gas Mileage Issue After Tuning w/ Diablosport
Hey Guys!
Over a week ago I got a new Diablosport Predator Tuner and put the 91 Octane Race Tune on my 2010 Mustang GT. I filled up my tank with 91 Octane last Saturday (a week ago) and set my trip meter to 0 so I could see what mileage I would get. I don't commute to work, I work in town close to home about 10 minutes a day. Last night, I've noticed I have a little less than 1/4 of a tank and only 180 miles driven. That is a HUGE difference in gas mileage! I don't know if the issue is related with the tune or what but something is definitely not right. Am I wrong? I don't really know what to so does anyone have any ideas?
Thank you!

More than likely he didn't adjust the options on whatever tune he installed. His revs per mile and rear end gear options are probably all wrong and the computer is registering the miles way off (too low). I'm sure he is driving much farther than it's registering. Reload the file, but set all the user editable features to accurate information BEFORE the upload takes place.
If you don't know how many "Revs per mile" your tires are either get the specs for your tires from the manufacturers website or www.tirerack.com
After you know everything is accurate, use a GPS to verify your odometer and miles per hour are reading accurately. If you don't have GPS, use mile markers on the interstate. It's not as accurate, but gives you a ballpark idea.

93 octane in Pensacola Florida as of today is $2.79 (average)

I topped-off today in Jackson, MS for $2.48/gal for regular. Closer to where I live near Vicksburg it's $2.66. But if you own a performance car, you sholdn't be getting too spun up over fuel mileage.

Nope, never do. If I was worried about MPG I would have bought a VW TDI not a Mustang.
