    Did they do any updates to the ECM?
    Did you have them run the overhead after they replaced the injectors?

    My DDEC knowledge is limited, but there is an update they should do when they replace injectors. I belive it has something to do with calibrating the ECM for the new injectors.

    When this isn't done, the result can be a lack of power, and "off" running truck (almost like a miss) and an increase of smoke. If you see smoke from the stacks that never used to be there, this is a good bet. Take it back and have them put it on the computer.

    If you didn't have the overhead run when the new injectors were installed, I would have that done now too. It could be that something is out of adjustment. That would also cause a lack of power.

    It's always better to replace all 6 as a flow tested set (if you can afford to.). Sometimes when injectors go out they can cause cylinder damage which can wear the rings down causing a loss of power. I would have the truck put on a laptop to check all the injectors. You can also pull them out and have them flow tested on a bench.

    Same thing happened to me in my Cat c 12 I went to the dealer and for $88 they took the s/n from the new injector, they feed the ecm with the # and position of the new injector and that did it. She runs and purrs like it should.
