Hey everyone just bought myself a 2006 2500 HD classic 4 door 4x4! First truck I ever buy its barely been 1 month and I love it!:woott: Rancher turned it in to buy himself a new ford and i snatched it the same day he gave it up. I want to learn more about the duramax that is why im here! Also it does have a few mods, Banks air intake, magnaflow exhaust, and Hypertech power programmer. Has good power but i have heard it can be better.
