Plus there is a slight delay between the time they detect water flow and when the heaters actually kick on.
When no water is turned on our pressure measures 10 not sure of the unit guessing psi and then when you turn on the shower the gas pressure drops to 2 which greatly reduces the water pressure.
If low pressure is due to the low flow showerhead for example and your tankless water heater cannot get the required water flow change the showerhead to a newer model.
