Gremlins! Little demons that steal power from the inside of the engine.

Once you give us a little more info we'll figure it out.

Sounds like the timing of the IP pump may not be set properly. That's about where mine is right now. The truck runs fine, but doesn't have the power it should. His best bet for more power is to take it in to a diesel shop and have them check and/or reset the timing. They'll also be able to check the injectors.
