Which should I believe, Power FC or AVC-R

Well the boost readings vary between the two. The Power FC I believe just plugs up to the map sensor and the AVC-R has its own pressure sensor that is T'ed with my boost gauge, going to one of the nipples on the UIM. So which one should I believe?

Neither they're both made by apexi ! :rlaugh:
but I'd say the AVCR is going to be more accurate especially above 15 psi...

the FD guys around here get higher readings with their boost gauges than with the PFC.

The PFC Commander has a known display error for boost. It will display a value lower than the correct one. The PFC still does the correct map look-up for the fuel/timing cells, it just displays wrong.

PFC displays absolute pressure. Altitude, temperature, and weather will affect the displayed values. Boost gauges display gage pressure. There lies a majority of the difference you may see between the two.
