I know that by changing the drive pulleys on a supercharger you can vary the boost levels but since so much is computer controlled, does the ecm (ecu) have a way to limit the upper level boost? Meaning like a bleed port or pop off valve or an electronic regulator? Something that limits the top boost of the supercharger?

I haven't had the cover off of my engine yet but does anyone know if there is a place to plumb in a boost gauge?

Thanks in advance
