Welcome to FTE. As mentioned, we do have a 6.0 section, so you might want to ask this there.
Do you have a check engine light? How many miles are on the truck? Getting the truck on a scanner that can run some tests would probably be useful.
Black smoke:
Caused by excessive fuel for the amount of air drawn into the cylinders. Some black smoke on hard accel or at higher altitudes is normal.
Excessive black smoke could result from restricted intake or exhaust, inoperative leaking or weak turbo, intake hose(s) leaks, leaking or worn injectors, fuel return or supply restriction, stuck Exhaust backPressure Regulator valve or solenoid. Also PCM inputs such as BARO MAP ICP or EBP sensors.
Blue or blue/white smoke:
Caused by insufficient fuel or oil consumption. Normal when engine is cold or idling for extended periods.
Excessive smoke could be caused by air in the fuel, contaminated fuel, loose or plugged injectors, worn or leaking injector o-rings, thermostat stuck open, oil consumption, or plugged crankcase depression regulator valve. Also PCM inputs such as MAP or ICP sensors.

Thanks for the reply, definitely alot to think about. I was thinking too much fuel (bad injector) or restricted/dirty air cleaner, however, I agree that a scanner is the answer right now. And btw, I did try to post using the link u provided and was not able to do so. I kept getting an error.

I'm happy to chime in on truck issues, but if you're having difficulties with the website, that's above my head. I'll see if I can find one of the moderators to just move this thread for you so you don't have to worry about asking again down there. If the thread disappears, make sure to look for it down in the 6.0 section.
