So i have a 09 F250 with the 6.4 in it and the other night i was driving home. After be on the interstate for about 10 miles i got off on my exit and punched it accelerator. the truck bogged down BADLY and blew white smoke out the exhaust. Called ford today jsut to see if they had heard about it. Turns out there is a problem with the air charger cooler??? its part of the emissions system.. I then mentioned that the filter regenerates itself for up to 30 miles continuously...they say that shouldn't happen and are looking at replacing basically the entire emissions system on the truck...just figured i would give yall a head up incase your having the same issues.

Clif notes:
After crusing for a while then applying full load to accelerator truck has white smoke = bad air charger cooler (that what ford calls it)
DPF regenerating for more than 30 miles = bad DPF
Just an FYI
