MitsuStyle - View Single Post - I can't boost lower than 14-15 PSI and I think my O2 sensor is out

How are you reading the O2 volts? That is a 0-1 volt sensor. You shouldn't be getting much over 1 volt ever. If it is sending 5 volts to the ECU, that could be a problem, I don't know if that input is designed to handle that much voltage.
