I got a 2013 Raptor a couple of weeks ago. I really like the truck, but it seems a bit sluggish. So, the good folks at VMP are sending me a tuner/tune, which should be here Monday. I have talked to a couple of people who said a new, performance tune made a night and day difference in their truck, so I have high hopes. Even if it's not "enough " I will need the tuner for the TVS kit anyway!
