You guys with the 6.0's. Have you had them sh*t out on you? I have 4 buddies with them, all with very similar problems. They run good then all of a sudden have a hard time getting out of their own way, and Bellow smoke like a freighttrain with no go. All of which are from '03 to '05. We thought they had the "bugs" worked out for the '03, but they are stilling getting the same problem and all the dealers they have been to tell them it has to do it when they have the trucks. We have about 15 7.3's around and the only problem that comes about is the CPS which tend to go out every 60-80K or so.
