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.

High Quality Product!

This tuner works wonders for the 7.3 powerstroke. It pushes the motor to redline and when the pedal is mashed, keeps it just below it, so you're running like a banshee throughout the power band! All of SCT's research and development have paid off in this unit. Super product I would highly recommend.

Noticeable HP & torque gains with 93 octane stock tune Increase MPG from 12.3mpg to 17.5mpg highway Would recommend to anyone Mods- Gibson shorty headers, Brisk USA LGS spark plugs, Granatelli wires, custom header back exhaust, Flowmaster super 10 muffler, K&N Blackhawk CAI, and SCT Tuner with custom tune Next on the wish list is a supercharger or pro charger Little pricey but worth the $$ Can't go wrong with SCT

I notice a difference in my shifting but I'm not sure about anything else. There is definitely not a extremely noticable difference that being said I do plan to buy a new tune soon and then hopfully I'll feel better about how much money I spent on this
