tap the manifold or get a superdiesel manifold and get a reading from there , you can get a reading from the wast gate line but its not as accurate, as for over boost codes they happen on some trucks and not on others , the Edge should override them as it tricks the sensor . The banks is good for any psi until you actually stop the wast gate from opening (just keep turning it to shorten it)
