Does anyone run their diesels with a chip or programmer or other diesel upgrades? How can you get away with running your truck with the mods without voiding the trucks warranty? I have an 06 F350 Powerstroke, and have been considering these mods. But I am afraid I may void my warranty if I install them, so I am just wondering how some of you with newer trucks with upgrades deal with this? If mods actually do void the warranty, I am not going to touch anything on the truck. Also, who makes a good setup that isn't really too expensive? If anyone does have a modded diesel, what kind of upgrades do you have on your truck, and what kind of a performance increase does it give you? Thanks.
