It obviously would have been cheaper than removing the pump, but they said, without calibrating the pump, the rest just causes more smoke or doesnt allow the pump to accuretely use it and messes with reliabilty. The smoke is unburnt fuel. No good for power and hard on the pocket, but good for tail gaters.

Messing with the pump after that point can be a futal effort and provide little to no change, except smoke and the pump sometimes sticks or causes more problems than it does good. Most want a quick fix and more power, but you cant change the pumps ability to flow without taking the pump off and only a tech with proper equipment (expensive) can set it. For your own sanity on this subject and for the sake of arguement, call Sam at the 800# and hell explain it.
Most cannot rebuild their own pump. Theirs a lot more in their than seals and gaskets. The tolerances must be set and there are upgrade parts (springs, rollers, bearings, etc....) to install for todays low grade diesel.
