    The only one I've had any experience with is the Hypertech and it worked great. I noticed in the latest issue of Sport Truck, they have "all" of the programmers and where to get them. It is a good read as it lets you know what each one does. Good luck!

    I got a POWER PUP from bully dog. Adds about 30 hp at the rear wheels. I also get about 2 -3 mpg better. But if you haven't done the Cold air intake and a better/ bigger muffler, you probabley won't see alot better mpg.

    Do you guys know if any of these power programmers affect the warranty in any way? I too, would love to squeeze more HP from my 6.0 (no, 367 is not enough :gasp:) but I don't want to jeopardize my warranty coverage.
