I must drive a lot like Ed as I get similar mileage to him. I also have a ScangaugeII. One of my favorite gauges on it is mpg gauge. It is real time and very surprising how often the truck is getting 30 plus mpg,or more. It also gets less than 5mpg just getting her rolling.I think the Scangauge has helped me get better at getting good mileage most of the time.My trucks electronics are still stock but would like to try a tune or tuner,and or an exhaust, but not till next year.
