Hmm, what is the white smoke?
If I had to guess, I would say it's the same thing that most of our trucks do when we first install the Delete kit.
I would venture an edcucated guess and say, it is a result of the forced regen.
When we first put on the delete kit's most of us see white smoke for a few miles or so. I beleive it is the computer ECM learning. Now, why yours did it is a good question.
You might have maybee cracked the DPF during the regen, they get HOT. very hot. maybee with the snow, it was just too many quick temp changes for it to handle and it cracked. that is my guess.
anyone? bueler? anyone?
