I've been looking to try to find a list of mods that actually helps increase mpg and I think that it would be a great addition to the FAQ. I know that at least for me, I would like to squeeze out as many mpg as I can. I'm no hypermiller, I just want to make the truck as efficient as possible and if a few mods can help than I'll do them. The only thing that I could find was Diesel Database :: Tips And Tricks For Better Fuel Economy but there has to be more mods and advice that people have. I haven't gotten a truck yet but will be getting one after I get back to the states. I am going to be modding the truck for longevity and fuel mileage since it will only be towing a maximum 6k lbs (at least 3 days a week in the mountains though). I'm not looking to gain a whole bunch of hp, just to get as many miles out of the truck as I can with the best fuel economy possible. I don't think I will need to increase hp for a 6k lb load. I was going to post a thread but before I clutter the board I thought that I'd post it up here.
