6.0 Issues - Black Smoke and Hesitation

A couple of issues...my 2004 6.0 runs very smooth. Have had no issues. However, when I apply the throttle to pass or power over hills I get a stream of black smoke. It has been mentioned that it may be running rich? Any ideas? Also, I get an intermittent chugging or hesitation on the highway when the engine is put under load. Any ideas comments is appreciated. Many thanks. Alan

is it stock? or do you have intake tuner and exhaust..... as for the black smoke it is normal.... the smoke starts to clear when the turbo builds more boost.... im sure when you going to pass your only at around 5PSI or lower so when you get on it esp if you only do it lightly enough to not down shift you will see plenty of smoke cause their is not enough air going in but once the turbo spools up a bit the smoke clears......

It is stock. Also, at low speed, I hear turbo noise but at higher speeds there does not seem to be much turbo noise. Do you think it is a possible boost issue? Should I buy a programmer?

i don't think the black smoke is anything to worry about... a programmer will only make you make more smoke lol.... it'll be pushing in more fuel for more power.... and intake and exhaust would be a good upgrade... you'll be seeing better MPG with the better flow.. also don't forget your gauges... that way you can monitor your boost and EGT's.... if you want safe reliable power that is an off the shelf item so easy to install the edge Evo programer with the attitude display is a good programmer... here is a link to what it looks like.... i have this on my personal truck....
Edge Products: Product

let me know if i can be any other help to ya...
