Purchased my 08 sprinter HT 170" last June with 104K on it to use it for a Moto Hauler and camper rather than a toyhauler/truck. It now has 122K of fun miles on it with trips from TN to FL, PA, and to CO. A few racing buddies both have the GDE tunes on their Sprinters and nothing but good things to say along with most sprinter-forum users on here t hat have performed reviews. So I decided to try it out. Had a hiccup during the install and had to repeate the process twice for some reason but once it did install correctly the van did start up easier and seemed to idle smoothly. In the cab I felt the engine noise became a smal bit more "tingy" but perhaps that's normal. I've had the tune on for about 5-10 tanks now with a definate increase in MPG. In East TN our weather has been crazy for the past couple months so one day its 70F and the next is 30F. However, I've been getting about 18 mpg during the winter months. Since the tune was installed, I've been getting a solid 2.5-4mpg depending on how much I can keep my foot out of it. I've averaged 22mpg driving around 72mph so far with the tune.
Now the question becomes to delete or not the DPF since I don't get smog tested...
