WOW! Here's the facts. I programmed my old Dodge Cummins 4x4 automatic trans to stage three. This truck is only used for towing and the FAQs reccommended stage 3. My previous towing milage was 14.6 mpg while towing 5000 lbs. Reprogrammed I got 21.4 mpg towing at 55mph on cruise, and 21.6 mpg towing at 60mph. This was towing over a 1200' grade during a 200 mile round trip. Milage while not towing is about the same, 22.4 mpg as opposed to the previous 18 mpg. I now cruise up hills the truck used to struggle on with excellent throttle response. My only regret about buying the Hypertech Energy Max is that I didn't buy it years ago and save myself thousands by now.
