I may not have explained the situation to you clearly.
Without the HFS-6 wired in ( this is your normal ECU to prodrive valve arrangment), if you unplug the harness to the prodrive valve, the boost should default to wastegate pressure -any outcome other than this - is not normal. This is regardless of how many years the system is in place and working correctly, it is still wrong.
Until you have tested this, the HFS-6's boost cut will never work properly. I am not rying to argue with you, I merely help you getting the HFS-6 failsafe working as it should.
