Thanks Richard,
I already got a adjustable pressure switch for clogged nozzle detection, I was planning for one stage injection that?s why I got one switch, I could get one extra switch and place both switches in each stage after block-off solenoids and before the nozzles for checking clogged nozzles. It is even possible to ad time relays to cut down the turbo pressure if the pressure switch stays on after turbo pressure switches go off.
