The more power you have the less you push the throttle to maintain speed, and accelerate, therefore the engine doesn't have to work as hard and you get better fuel economy. I run a 96 7.3 powerstroke with 272,000 of reliable service every single day. not the fastest truck or very good on fuel towing but it works every day during the spring, summer and fall and to me that is what counts, i know a gas truck wouldn't be able to move some of the stuff i tow with my truck. or it would be going very very slow up some of the hills around me. getting 4 mpg probably.
That isn't the case with the Dodge. It gets better mpg on mild +60 hp towing than on hot +175hp. Empty it does better on hot.
