Rough idle problem

[TheTankF25010]

I was driving home doing 70 mph for about 12 miles then had to stop at a light when I got into town. After sitting at the light for a couple of seconds my truck started to idle rough and shake a little left to right. It almost sounded like it was missing. Then the light turned green and it drove normal and hasn't done it since. The only thing I noticed is my turbos sounded louder in the stop and go after that, but after a little while they went back to normal sounding. Me being me and only having 2200 miles on it started to freak out. I called my Ford dealer and they said it might have been in regen. I didn't notice the message but it wouldn't have been the first time that I've missed the message. I don't have any check engine lights and flushed my water separator under the cab to make sure there wasn't any water. There wasn't any that I could tell. I wouldn't think bad diesel because I always fill up at the same high traffic station. Bottom line any one have any ideas and should I really be worried? I am ordering a spartan and dpf delete today and don't want to have to worry about taking the truck in right after installing them.

I've noticed the same thing on my 08 during regen...no big deal.

The motor will usually have a more raspy sound to it whenever its in regen. I usually missed my message on my screen when it was on because is comes on for a few sec then is gone but stays in regen for a little bit, but i knew because of the motor noise being more raspy.. But SCT and a dpf/doc solved that

Yep...you hit a regen
