I was out cruising yesterday trying to get some driving time in before my brother takes over the payments on my car. I was at a stoplight next to a 4x4 crew cab Duramax diesel with a shell on it. I'm not sure what year model it was, I don't know much about Chevys but it was pretty new looking. Thought nothing of it until the passenger in the truck asked if I wanted to run 'em (I was in the right lane, they were in the left lane). I looked around, saw no one in sight and said sure. Light turns green, we both launch the shit out of our cars/trucks and to my surprise he was right there with me through second gear. I started pulling on him top of second, threw it in third and had about 1.5-2 cars on him by the time I let off at 65. I looked in my mirror and couldn't see anything but black smoke haha. My car is all stock sans the cat back exhaust. I know people tune diesels to run pretty damn quick and some even get to the 10s, I just never seen it in person. Those diesels are sleepers!
