So long as they are taking readings from the same place I would think they should be fairly equal. They do match readings once in a while. It may just be a bad connection with vibration. Have you tried securing the connection at the sensor and it is possible a sensor is bad. My money goes with a bad connection because it's too erratic.
Have you swapped connectors to see if the problem changes sides? That may rule out a bad sensor and removing and securing the connectors may solve or rule in a bad connection.

Rob,

What's your take on this?

I agree Roger, the 912iS sport upgrade comes with a new aluminium rack to support the sensor connectors. Make sure the wires are tie-wrapped nice and tight to the rack.
If you don't have the Sport upgrade then tie-wrap the connector wires to each other so they don't vibrate.
