1st tank results
I just got back from Wisconsin and my wife was still on the 1st tank since installing the EcoTune from GDE. The low fuel light just came on this morning...I was hoping she wouldn't have to fill up before I came home, so I could fill the tank to the top of the neck like I did when I filled it up last time. Luckily, she didn't have to. I just filled up and here are the results: 506.9 miles (GPS verified)/21.387 gallons = 23.7 MPG. Her driving is probably 60-75% highway. I am very happy with those results. She drove the previous tank in my Jeep as well and the results were 20.1 under the same conditions. I do think, however, that she drove with a slightly lighter foot than normal once she saw how much better the EVIC was reading after the tune (EVIC reads between 3.5 to 4.5 low BTW). She kind of got excited about getting 500 miles from a tank, once I told her she was on track for that. I will be keeping track of at least the first several tanks with the tune and post results.
Thanks to everyone for taking the time to post results on here. I have been wanting to do the GDE tune for a while, but just didn't believe it would work this well until I read so many positive results with ZERO negative ones. Like everyone else says, "I wish I would have done it sooner." True...true.
