My neighbor has a 02 Chevy with the duramax and he is looking for info on how to get a little extra grunt out of it. He uses it for work and really isnt interested in hard core mods or the like just a little extra when he has some weight on it. 
I figured the best place to steer him to would be a board similar to this that caters to the late model GM truck crowd. Anyone know of one?
TIA
