I wonder if my MAP sensor is fubar. My BARO reading is 11. I'm at 4500 ft, but even so, the BARO should read higher than that. When my truck is idling, the BOOST reads 13; BARO reads 11. Local reading from mercury barometer is generally around 650 mmHg, which converts to 12.6 psi. So the BOOST reading seems accurate, but the BARO does not. I doubt I'm getting 2 psi of boost at idle, right?

Readings are from AutoEnginuity.

Disconnect the vacuum line to the wg, note the sensor output
