serious smoke
I have a 2006 ram 5.9. I spend winters on the Texas coast(sea level) and the summers in Gunnison CO (7700 ft asl). All is good at sea level but at 7700 ft I get serious black smoke just driving around...

Black smoke is a sign of not enough boost, or too much fuel, check the pressurized side of the intake system boots and inter-cooler for leaks.
If the waste gate is malfunctioning either stuck full or partially open it would slow the turbine speed(reducing the boost pressure), less air/boost you get smoke.(over fuelling)
Primary function of the waste gate is to regulate boost pressures in the turbo, basically to protect both the turbo and the engine.
Work around some big gas Cats 3512, 3516, 3306 and 3520s, when a waste goes on one of these, you not only hear it but see it blowing some good smoke out their stacks!
