    Best Chip for my truck

    I'm new to the duramax world so be easy on me but I've got a buddy who ha his 08 SilveradoHD chipped, hes not sure what kind he bought it that way, but all I know is it hauls ass down the road and leaves mines in a cloud of smoke. The only real thing I know about the set up is that he has 3 fuel...
