Debate still open on that.
There is an TSB regarding "aftermarket" air filters.
They don't mention the BHAF, it leans more towards oiled filters.

I have had mine into the Dealer for 2 oil changes since I got mine, and they didn't say anything about it,
yet.

I spoke to the service manager yesterday because I wanted this looked at and he said he didnt know much about diesels and said he called a freind of his and then suggested I try a k&n but I hear to much bad about them.will I like the bhaf or should I just get a stock filter

 

I don't think it is your air filter. If it was you should be seeing lots of smoke. I was wondering, have you been following the thread over in the 24v forums about the same thing? Have you checked the fuel pressure? I also wonder about the possibility of an electrical issue. These trucks should get a lot better mileage than what you are getting. I still wonder about the no the no codes. Seems like it should have thrown a code somewhere. What kind of mileage do you calculate by hand? Does it agree with the display?

im getting about 1mpg difference manually calculating napa doesnt have the bhaf in stock so im going to try the fuel filter the crankcase bottle is nasty on the outside so I dont think the thing has been maintained very well there doesnt seem to be any scratches on the plastic cover on the fuel filter either

 

put the fuel filter in and cycled the pump 4 times it sounded like it was spinning fast and no start did it about 10 more times and about had a heart attack when it wouldnt start ran it again and opened the water drain and fuel was going through did this a few times then the pump sounded like it was struggling but it started running thank god. Is this a bad lift pump or did I do it wrong ill let you know if the mpg gets better

 

Sounds to me like you really need to check your lift pump pressure.
