Made a huge difference in throttle response, shifting points, power, and in towing on my 2013 F150 FX4 5.0. I have noticed a little bit of an improvement on mpg's for around town driving which is what I primarily do but have not got to test highway mileage yet. Also, I have a K&N intake on my truck. The programmer does have a preloaded tune for the JLT intake but no other intakes.. I do wish there were more options to select on that note.
