What yr model 5.9? 03-05 5.9 fuel systems had a tendence to self contaminate causing inj. issues and eventual eng. failure,there was a recall to patch this problem, PM me the full 17 digit VIN ## and I can check it for you to see if and when the recall was done.
6.7 don't get the mpg the 5.9 does, the 07-09 had a lot of check eng light problems mostly programing issues. and when it is soccer mom'ed or grampaw'ed daily they get emission carbon build up and will need servicing.
This post kinda makes me wonder if it was really the Edge pressure box that caused my problems in my 2003. I dumped an injector, flooded the crankcase with fuel, burned up the turbo... all while loaded with 200 or so square bales on a 32' trailer, 120 miles from home. It wasn't a fun day.

Chris I ran my 05 for about 70k with bully dog performance setting on it. performance is suposed to add timming only
I went through 2 sets of injectors before the truck made it to 150k and got traded off when the second set started going out. My mechanic said it is all from the new fuel not being oily enough to keep the injector pistons moving freely. He recodmends putting one quart of trans fluid in the fuel at each fill up. his service truck has 3xxk and no injector problems to date.
The injectors for the CR are not 150 bucks a piece as stated above, a set will run around 2k no matter how you slice it.
