Default Sudden gas milage drop..

i always do the same drive from chicago to missouri and always got around 18.0-18.5 mpg with the cruise locked at 70mph... my truck was at the dealer for some other work and when i picked it up the service d.b. said they did a number of computer updates but couldnt tell me what any of them were. now on my trip down and back this weekend my milage was no better than 16.2 mpg according to the evic and the rpm was at 2000rpm at 70mph. has anyone else seen a drop in milage after the computer updates. also seems to me like the mds doesnt kick on like it used to (but i've never seen the light either except when i start it). was kinda shock to see how much it dropped.
