Switch should trip at 1.15 bar or so. I assume trip boost will vary according to age and switch tolerances. Switch will effectivly disconnect when trip boost is reached and it will shut both fuel pumps.

I recomend to leave the switch in the loop as it's your only safeguard should wastegate pressure line or membrane develop a leak. I sure tripped mine before I found out my membrane was shot.

Also if BOV is not working correctly, switch might trip inadvertly during shifts as boost will spike when you lift off the throttle.
Thank you for your time,
