yeah, but gotta be careful with tuners. The canned type (edge, bully dog, etc) that you just buy off the shelf and plug in don't do anything with an auto trans and will fry them pretty quickly with a lot of high HP tunes used. Plus some diesels don't have the internals for them (6.0 powerstroke toque to yield head bolts). Hence why *I* wouldn't be buying one without head studs and a few other things added.
Custom tunes are a bit pricier, but they're written specifically for YOUR engine/trans combination, plus they can be written for specific uses, too. There's a few good companies out there, but since I know fords best, don't ask me about what tuner companies work best for dodge/chevy. I'd only suggest innovative for pretty much everything...
