Actually, I believe the Missing Link limits the actual pressure, so the sensor never sees boost (someone correct me if I'm wrong). So stopping the problem by never showing the MAP boost, just showing it vacuum.

You can also "clamp" the voltage, in other words the MAP will see both vacuum AND boost, but when it tries to tell the ECU that it saw boost, the clamp limits the maximum voltage, so the ECU has no idea that you went into boost.
