It's all right D. The chevy guys are just jealous! You do need to put a turbo-back 4" exhaust, an improved air intake and a BD performance "chip" on that 6.0. Then you'll know what power is all about. Actually these are fairly decent in stock trim, but the add-ons really make them come alive. All the big diesel burners are expensive to repair, so it pays to do your maintenance. Enjoy, Eagleye.
