I have an 06 Dodge 2500 with automatic and tow package. Put on after market cold air induction and 5 inch cat back exhaust. Added the Edge Mileage Max and boom, mileage on overhead computer reads 27 to 28 mpg constantly. Figuring actual mpg (miles driven divided by amount of fuel) and I get 16.1 on the highway at 65 not towing. Have kept service up to date. Other than poor mileage anyone have an idea as to how I might get better mpg. I called Edge about it, they were about as helpful as a dead slug. Edge Mileage Max did increase power but took my mileage down from stock condition by about 5 mpg.As far as I am concerned Edge can jump off the bridge.
Overall the truck is great. Plenty of power and strong as a horse. Over 47,000 miles with up keep service and I have not had a problem other than with my EDGE Mileage Max. This is my second one. First was a '71 which I traded in on the '06.
Add a step to the side or rear so us short fellas can get up to the bed in a 4 wheel drive.
