Had local dealer load my Pro-cal tune on my 2013 GT at 12,000 miles. I do notice much better throttle response (and the occassional ping). However, I was hoping mileage would increase by 1-2 mpg. I do have the Track Pack with 3.73 gears, but my mileage is checking the same to even 1/2 mpg less than before.
Anything I need to check on the Pro Cal?
