So I recently purchased a p3 gauge and was wondering if I got the obd2 spliter and ran the Cobb ap aswell. All I want to do is run vacuum/analog boost in the p3. Would the cobb ap gauges not work. Or would they because the p3 is reading vacuum where the ap is reading from the ecu?

multiple OBD devices is generally a no-go... it's designed to communicate with the ECU with a single device only, as many of the comms are request-response model.
You should run the non OBD P3 gauge if you want to use it at the same time as the AP, otherwise you'll have to unplug one of them.
