white / Gray Smoke ??????

Guys I need your Brain power here. I have a 08 f-350 with a H&S black maxx, cold air and 5in exhaust. After I drive the truck for a while (30 to 45 min) and let every thing get warmed up, I get a lot of white / gray smoke from the exhaust when the truck is at a idle after idling for 30 sec to 1 min. Once i accelerate for example taking off from a green light it stops until I hit a red light. I took it to my dealer and they said that its normal because the dpf would clean the smoke out before I removed it. I call B.S.

I agree to B.S. White smoke could be a couple things, but I would bet EGR issue. Are you slowly losing any coolant with no leaks seen?

Eating coolant is what comes to mind.

I'm not sure what the impact of the EGR being "Turned Off" would be but I do know that the Black max will allow you to disable the EGR without removing it. Could that be having some sort of impact. Do you have your's disabled?
