Boost Sensor for MSA12/15 & Vacuum Systems

Hi,

Does anyone know how the boost pressure sensor installed in the engine control unit (ECU) of an MSA12 or MSA15 responds to vacuum (sometimes strong vacuum)?

The context is my planned bypass valve, which would "close" before the intake manifold. The leaking pistons would then "suck" aggressively on the engine control unit.

If the sensor can't handle that, the "tapping" needs to be directed somewhere else.
