Just a new guy but my 2011 was kind of a pig, I went with a 4" turbo back, H&S mini max, S&B intake, full delete and used the H&S trans tune, the system is incredible, the power feels double, the mileage went up quite a bit, got the full deal for around 2k, put 10,000 miles on it set up this way without a hic up, I love it and glad I did it.

By the calculator almost 20 on a good day, seems to stay there at 75 mph, a little slower or faster drops to around 19. About 17 on a good day stock, thats also running 33" tires before and after mods.
