I recently had my injectors tested at a diesel injection shop. One of the injectors was a bit off, shooting a stream of diesel. I had it rebuilt at a cost of about $75. Can't tell you if mileage improved...had a mishap with the return lines and one ended up popping off on a trip to NJ. Before I was getting a solid 30 mpgs in the winter running with power service. I'll give you an update on any improved mileage. Just to let you know, if you do want to get the injectors out, you NEED to get the special tool from the dealer or phil at fastlane. I needed it quick so went to the dealer to drop $35 on it. Its just an extra long socket, about 5-6 inches long.

oh yeah, dont forget to get 6 new crush washers for the injectors when you put them back in.
