I'm in Lenexa. I have had an issue with the egr but that appeared when coming back from Oklahoma. Found a Ford tech through a friend of a friend in Joplin that does side work. That was last August.
Recently, I've been researching injectors as I'm getting 10s mpgs. Had a distribution test done back in Jan by someone off CL. Waited till 3 weeks ago to get it looked at. Found Association of Diesel Specialist
and found 2 local businesses - St. Joseph Diesel and Blue Springs Diesel. Called both. Blue Springs doesn't work on the actual vehicle, they perform bench work. He lead me to B&J Auto in Odessa. Guy talked me into looking at other possible problems since I had a c&c truck and not a pickup.
He drove and tested the truck. He found the injectors working fine, but found the tank coating deteriorating away (metal tank). Pulled that, cleaned it out, recoated and the fuel pump was trashed. New pump and everything was good for a day. Then engine started missing, turned out injector #7. Replaced that. It ran fine for him and for a day.
He also reflashed the ECM and FICM. I have the SCT and had to get new tunes for the new strategy. I haven't installed them yet. Used the truck to pull my Jeep on a trailer last weekend (basic use of the truck). Went about 1/2 tank for the 200 miles but the turbo gauge wasn't working. Found the connector wasn't really attached so that might have a lot to do with the mpgs.
That's my experience for owning a 05 6.0l.
