![]() If you're only getting 15mpg you are either putting your foot down too much, you have enough mods for your car to be considered a drag car only, or you have tuning issues. My last Stang ran mid 13's and got 18mpg even with my lead foot. That was with 3.73 gears. Your car is a bit heavier so that will make some difference, but I can't see 15mpg on a daily driven Stang. More info is needed, but generally stepping up in gear size isn't going to make a ton of difference unless you do a lot of highway driving. And even then it won't be so much you should regret the gear swap. 75% of my driving was on the highway and I never really noticed any difference myself.
