I am in no way talking smack about Duramax's because I respect all diesels. I am simply wondering because there is a kid at my college talking smack about how my engine is old, outdated, and gutless. I told him I would tow him around the block and back and to put his money where his mouth is. Now, I rarely talk smack because its just not my thing. However, this guy pissed me off. Hes got a 2004 with Banks tuner, wastegate, and a straight pipe. I am leery because I know what these trucks are capable of, but I think I could probably take him in a pull. What do you guys think? Mods are in my sig. I don't have the head back from the machinist yet, so no injectors, no headstuds, and no fire rings yet. Should I wait, or just go for it?
