I have been thinking about getting a set of pacesetter long tubes and a bully dog tunner for my 02 2500hd with the 6.0. I was wondering if the bully dog will give me the ability to tune the truck for the headers, if it needs it at all? I can take care of the work to install the headers and run my new exhaust its just the computer/ tuning buiness that i am not sure about. Thanks, o3gerber
