Nobody tunes a Mustang to see how efficient it can be! (Well, there probably is that guy out there.) If you've purchased a tune and supporting bolt-ons, odds are you're gonna want to see what it can do... Which probably means a slight drop in MPGs from what it could be. I've read many claims that mild tunes often improve efficiency, but I wouldn't know that.

I'm just curious what kind of mpg change people are seeing after a tune?

There's no real reason why light mods and a tune will decrease mileage when cruising by much if at all. Usually tunes and such make the engine more power when accelerating hard, but at cruise and light throttle they ain't messing with it much to really affect efficiency.

FP Stage 2 w/Solo Perf cat back. Best ever on long trip 25.5mpg. Normal mostly hiway 23.5mpg. Around town about 14.5mpg. Whenever I want to have fun-terrible mpg. But then, who cares? Most of the time I don’t even look at mpg. I just pull in and fill it up with premium and go. Only use Shell, don’t shop price, and have never had a fuel related problem.
