both, you need the pump to ensure that you are getting enough fuel when you are on it, and you need a adjustable fuel pressure regulator to regulate the amount of fuel going to the injectors, at the stage you are at right now with your mods don't bother messing with the fuel pump or regulator unless the pump goes out.
