I've found out so far that the avc-r only regulates boost up to 28.5 PSI. Maybe the pressure sensor can go above that but i don't know. The Zeitronix 50PSI MAP can measure boost up to 35.3 PSI. I also found out that all MAP's are pretty much linear. I guess i can run 35 PSI through my air compressor into the apexi sensor and see what voltage i get? Could this damage the sensor?
