Turbo howl when cold?
When I remote start my truck in the morning I can hear the turbo have sort of a howl, not the turbo whine I'm used to. I always warm it up for 5 minutes minimum before I drive it. FOr the first few miles the howl gets noticeably louder when I let off the gas at a stop sign or light.
Has anyone else noticed this?

Mine has a slight whine as well for 1 - 2 minutes (built 12/2/10).

6.0 owners with the mods and tuners and don't do the proper maintenance are right up there.
Do you know of a way to get rid of that howl on the Forums?

I have another idea too. If you look at the cutaway picture of the DEF chamber, there is what appears to be a spinning auger type thing and I kinda think I hear a motorized whirling sound down in that area as well. I do hear the turbo howl, but I also think there is sound from the DEF chamber combined with it. Just a thought. It all goes away when temps get above 80 degrees or so (engine oil temp).
And yes, i've heard some really loud 6.0's at startup and they sound like turbine engines....
