i have a 06 6.0 with 231k miles on it. It has never smoked. We just pulled into Colorado Springs and noticed when I accelerate it is blowing puffs of black smoke. Power seems fine no other issue. My EGR is deleted and I run Matt Gearheads 8k tune. Just curious we are headed to Yellowstone this week and want to make sure it's in tip top shape.

I read it could be related to the altitude? Anyone else think that's possible?

You may want to check and see if your Baro sensor has compenstaed for the altitude change. I really do not remember the exact rate of change but depending on your altitude somewhere around 15 I would guess.

 

 

Lol on pikes peak today and I couldn't breath. Just headed to Yellowstone later this week with a RV and wasn't sure. It doesn't do it at home :-)

 

You lose approximately .5 PSI for every 1000 feet of elevation increase so at an altitude of 6000 feet above sea level you would have about 12 PSI on the BARO.

 

Map sensor reading is 11.6 truck runs fine. Headed to Yellowstone tomorrow. Thanks
