Help Please.....DMAX OWNER

[dmax03]

My gf mother has a 2006 PSD Dually S/B with a superchips max micro tuner, and straight piped and recently it has been smelling like diesel in the cab, so much that its making her have head aches, and on sunday i noticed when she started the truck and it was idleing greyish smoke was comming out of the exhaust.
I know on Duramax's thats a sign of injector problems, and i have not had a chance to check for fuel in the oil b/c of the rain today.

Any help would be appreciated.
P.S I work for FORD in sales so dont hate me just b/c i drive a dmax....HAHA Im over on the duramaxforum all the time

Did she have any work done on the truck recently?
On my Lemon, they shop forgot to hook up 'something' correctly, and we had the same thing, although mine smelled more like jet fuel than diesel. The dealer would or could not tell me what they had found, but it was almost like the smell was coming through the firewall somehow.

Check oil oil and coolant levels. Is it smelling like exhaust in the cab. Being an 06 you should still be under warranty. Take it in and have it checked
