My manifold pressure is unstable (ever since flight 1). I have G3X with the standard transducer supplied with that engine package. Unlike the Vans construction manual, I tapped the MP off #6 cylinder (closer to the connection point on the firewall). Does anyone think this could be a bad transducer, or just a bad choice of where to tap off the MP? Readings during flight bounce up and down +/- .5 in.
