Talked to one of BD's guys at Indy yesturday about the problems with the C/C trucks and programmers. He told me the camshaft is different from the regular 2500 and 3500 trucks. He said their new programmer will work but the timing is rough due to the camshaft. Not sure if this is true but I'm going to try and find out.

So the C&C's have a better timeshaft from the factory, causing the box's timing advance to be too much?

Yes, According to him the timing is too much. Now as far as the cam being better, don't know about that.

More cam lope would equate to less low end torque from more duration. The sound difference is more likely the difference in the exhaust systems.

Do the late model 5.9s use the same cam as the 6.7s? Does anyone have the duration and lift specs for these cams?

I'm going to say no, but I don't know for sure. There are a few shops that have the 3rd Gen 5.9 cam specs but won't give them out.
