So I've been combing through threads and posts looking for some definitive mpg increases and haven't come up with anything concrete. Figured I would try starting a thread where we can really think tank some mods up to help increase the mileage on an 800 series truck with the Cummins 250. I've heard alot of it just is what it is and get a different truck if you want fuel mileage, but that's not good enough, I know some ingenuity from members here can think up something. I'm not talking a fantasy number like 20mpg, but I think 10mpg is a realistic goal for an unloaded truck. Below I've listed some of the more common ideas for improved power and mpg etc. that I've read or heard about, I'd love to hear some qualified experience with these mods or some experienced thoughts. Thanks all, I can't wait to read the replies.
-Dual fuel line split
-Add turbo
-Bobbing the rear axle
-Bigger tires (48's or 53's)
-Front sprague disengage switch
-Bigger fuel button
-Transmission swap for a 10 speed
-Removing a few leaf springs
-Cut down on weight/streamlining (this one was funny to me, there's no streamlining a brick, and my 818 doesn't exactly have alot of unnecessary weight on it)
