The
pressure switch is not a regulator it has nothing to do with the pump, It only controls what level of boost your pump will activate. The pump pressure is based on nozzle size, the smaller the nozzle the higher the pressure. The
pressure switch on top of the pump will only take or add around 15psi of pressure we recommend you just leave it set were it is.
The
Progressive Controller is the only thing that can make big changes to pump output pressure through pulse width modulation.
