It wont matter what pump you use its the fuel pressure regulator that will determine the pressure, 300 kpa sounds about right.

Nistune can't adjust your fuel pressure though. You'll need an aftermarket fuel pressure regulator to change anything.

Yeah the nistune wont fix your problem, well you could try to tune around shit fuel pressure. It could be as simple as a blocked fuel filter. Get the fuel pressure and flow checked using a gauge. Most places should have a half decent setup. Fix the fuel system problem before trying to tune af mixtures.

Fuel pressure should be about 43psi from memory.
