I have a 2004 F250, Harley Davidson Edition of course, with the 6.0 Turbo Deisel. If you had a budget of $2000 what would be your engine Mods you would do? I use the truck primariyl as a daily driver but it does tow a 9 thousand pound fifth wheel as well over a variety of terrain including mountains. I am looking for more fuel economy as well as more power without haveing to do the Head bolt switch yet. I can do the work just need the suggestions. Thanks.
