Limited to 110mph. Rev limiter, Trans shift points, and speed limiter options not available. The economy tune has almost as much power as max effort and will get you good mpg if you keep your foot out of it. This review is when used with a 2006 ram Cummins. max displayed mpg was 36.9 actual was 31. Its very easy to get 26 shown and keep it there. This yield an Average mpg calculations were about 22 to 26.
In extreme level and extreme level. My 2009 GMC 2500 HD Duramax will do a quarter mile run and 10.3 seconds and 0 to 60 test and just under 6 seconds that's both from a dead stop no pre throttling straight mash to the floor when the light turns green I highly recommend this tuner it will turn your truck into a damn rocket in the amount of torque that it adds thank God it's got an Allison transmission cuz a weaker transmission would not survive it
The smarty j06 does everything I hoped it would and even more! Easily the best investment I’ve made towards my truck so far, could not be any happier and would definitely recommend to anyone with a dodge wanting to get the most out of their truck.
It was refreshing to have had a great buying experience with dieselprogrammers.com. Their knowledge and responsiveness to my questions made me very comfortable to choose the SCT X4 for my Superduty Powerstroke. Even though I was shopping for an entry level plug and play tuner, they spent the time to answer my questions and make recommendations based on my specific truck and use. II am very happy with the tuner but happier with the excellent customer service. Free overnight shipping was the icing on the cake. Thanks again!
Everything is perfect great power gains and got over 20 mpg on a 800mile trip. Also very helpful staff responded very quickly with any questions I had. Great company will be using again.-Josh, 2013 F450
