were you able to check the timing of your injection pump with a scan tool, setting the injection timing can be very difficult on these 6.5's the injection pumps also have stepper motors on them that can advance and retard timing so maybe the stepper motor is bad or stuck and making the timing off and causing it to smoke and have little power. you could try tapping the stepper motor lightly to see if it makes a difference.. just something to consider before spending lots of cash . good luck
