Give Jeff at SVC Off road a call. They have a brand new version X4 tune. I just loaded it on my truck yesterday. I had their tune on my other truck that I sold last year. I really missed not having the tune. Definitely works magic on the performance of the Raptor. You need to wake up this sleeping beauty. You will not gain any significant horse power but you will get better acceleration, no fishing for gears, the truck will run crisp. BUT I suggest getting a pedal commander too at the same time from them. The difference would be night and day. Pedal commander is plug and play. There are multiple threads regarding it. Definitely get it.
Your gas mileage will NOT increase but rather decrease somewhat. But that is expected you will have your foot buried in a lot more for sure. Good luck
Your avatar picture is pretty depressing BTW.
