This instrument did not work at all for me, as it does not read actual manifold pressure, but only the difference between ambient pressure and manifold pressure. Before I installed it I took it with me on a flight in a pressurized aircraft. At 8000 cabin altitude it was reading (you guessed it) 30 of manifold pressure. The case is not sealed at all, and therefore all it is capable of measuring is differential.
