Somethings definitely wrong there. A tune has actually been proven countless times to actually increase MPG. I picked up about 3-4 MPG in my 2011 GT
when Bama tuned it! To see a decrease of 10+ MPG just doesn't make any sense. Are you calculating this yourself and doing the math? Because the on board calculator has never been very accurate!
Also, could it be that you're driving the car a little harder now since it's tuned? We can definitely look into this again for you and try and help figure out what's going on. Maybe it's time for a tune up, plugs, wires, fuel filter etc...
