Your absolutely right in saying the cummins engineers designed an engine to pull a loaded bread truck around and still get 25 mpg. But my concern is not with "turning the engine up" and pushing its limits. My question pertained to using this engine in a much different application, using it in a vehicle half the weight of a bread truck and using it strictly for mileage. I was only curious as to what some people who have done what I am asking have seen for best fuel economy. I personally have not had a lot of experience with these particular engines, so I'm not arguing anything, but remember cummins engineers designed and built these engines to perform well in a variety of conditions and applications, and on a budget as well. There are always improvements that can be made to a factory made machine, that's what I believe personally, it just depends how much money you want to spend. Don't take this the wrong way, I just don't want this thread to turn into a pi$$ing match about "turning up" these engines.
