Question about injection pump

[Ramafid]

Which places more strain on the injection pump, Big injectors (DD2's) or a big fueling box ( Comp) ? I know the box makes the pump work harder but do the injectors? I'm trying to decide between the two. Then again maybe I should go with a larger turbo?

Any of the wire-tap boxes strain the injection pump. They are basically asking the pump to do something it is not designed to do. Most work ok, but sometimes a quick pump failure can be the result of adding a fueling box. In most cases, it is fuel-supply related. Injectors add little or no strain to the pump.
