Hey everyone. im jeff and im from the dfw metroplex. ive now got a chevy avalanche but im wanting a diesel. my brother has a 2003 F250 with some mods like superchips tuner. at first i wanted a new F250 but the other day i saw a highly modded duramax and as it passed me he hit the gas and sooted everywhere. i was like HOLY $%#@. im pretty sure ill get it in the next couple of months now i just have to look for a good price. (hopefully thell be cheaper since the new silverado's just came out) any first off mods i should be lookin into right as i get it? thanks for all your help
