Powercurve performance ended up getting 300hp out of a ZD30. F55 turbo i think , +90% injectors , remap , custom intake manifold.

Just wondering, why did you fit a lift pump? any reason behind it?

Main reasons I think are to take pressure off injector pump and provide more fuel if chipped or remapped? Many people do it. If it helps delay a $4k injector pump replacement may be worth doing

several things.
one is recovering lost performance. as the pump wears timing tends to retard. the bit of extra pressure helps with that.
the other main one is keeping air out. the injection pump has to lift fuel up from the tank and through the filter. filter restriction causes injection timing to retard, but also air can be sucked in through cracked hoses and filter primer seals. by putting it under pressure any leaks are exposed and it stops air from being sucked in.

also really handy for fuel filter changes. just swap filter, run the lift pump and its all primed and ready to go. no having to use that manual primer.

keep it under 15psi, needs to be fairly high flow, and must have a bypass valve fitted so the injection pump can suck fuel through when pump isn't running.
there is a few threads on it and especially on patrol forums.
