John, 
I don't quite understand why you flushed the turbo bypass valve with WD40?
the turbo bypass valve is a vacuum diaphragm valve that is connected to
your "turbo out", at idle the vacuums pulls the valve open and the boost is
dumped. 
Where is the boost dumped? 
I am not aware that there is an electrical connection in the  bypass boost
valve, please clarify.
I am thinking about adding an valve to my 5K.
