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

replace the o2 sensor, if you ever get more then 1volt then the 12volt heater wire is shorting out somehow inside the sensor and some of the voltage is bleeding off into the data wire going to your ecu.......so imagine if all of a sudden 12 volts jumped down a line into your ecu where the ecu is only equipped to handle 1volt.

get a joeP MBC, they are pretty good.
