Those Duramax are something else. My buddy has a 1 ton dually and he can light up the all 4 backs. He races it at our local 1/8mile strip and leaving on the wood in 4 wheel drive (it'll spin if not in 4x4) the thing is quick. I want to say high 9's but dont quote me.
There is an article in a magazine I have were they put a nitrous system on a duramax and made 1600 ft/lbs of tourque!!!
