2002 3/4 ton Duramax. Bought it in the spring with 76,xxx miles on it. Had the injectors replaced at 65,xxx. Its got 94,xxx on it now. Most of them were from towing a 28' tag at 10,000 lbs. I put a Banks programmer on it with exhaust and K & N filter I bought off ebay used. I also run some Bio Diesel in it. Its impressive. It pulls the hills here in the midwest w/o clicking out of overdrive. Low teens towing 70mph.
I took it to the track here on t&t night and let the fiance drive it. Was running low 14's with a 2.5 sec short time
