catmastertech :

Usually, black smoke means, not enough air. Have you inspected the turbo and test the boost pressure to the engine?

catmastertech :

Is travel the only issue? Does the engine stall when any other function is fully extended or retracted?

catmastertech :

I assume you have removed the air filters to see if it changed the smoke problem. I have see inner filters plug and looked OK but, they were plugged from working near ash and soot.

catmastertech :

OOPS- I just saw the notes of what you tried. Are you saying the intercooler was blocked on the inside (boost air) or the outside (fan air)?

catmastertech :

The best check you can do is to install a pressure gauge in the intake (a small port should be near the inlet pipe). A pressure of 15 psi to 20 psi is good. Engine must be loaded to get the boost pressure up.
