My 5.9 smoked more when it was new. It seems to have calmed down a bit now though. Maybe just give it some time to break in a little more. It will smoke anyway if you tramp on it, but just a little touch should not be doing that. Have you checked your mileage yet, maybe overfueling?? Or as said before problem with the air supply/turbo.

 

did it just start or has it always been like this?

if it just started check your intercooler boots

 

I would have to say dirty air filter. That would be my first place to look. My truck is also fully stock and I get a lot of smoke when I step on it. Seriously though when my air filter gets dirty it will smoke real bad.

 

I wish mine would produce smoke like that [8D]. I turned my programmer up all the way, though I drive it easy anyways. But when I do get on it, I see some smoke now.

 

Why is it such a big deal? It's a diesel. It's gonna smoke.

 

When I had my stock exhaust on my 06 5.9 I would geta good little cloud of smoke if I got on it hard after a day of driving really easy. But ever since I put my MBRP catback on, I rarely ever see any smoke at all. Dunno why that is though

 

Yeah. hum hum hum.... I don't like smoke either... hum hum.. I also don't like



or




or



hum...hum.. yeah I don't like any of it..

 

lol behind bars, thats was funny!

im all reality there are diffrent strokes for diffrent folks but please deano, if you find the problem to your truck let me know so i can adjust my truck to smoke like a chimney

 

Mine smokes when I get on it is supposed to be an ultra clean diesel. I like the smoke.
