Dan,
Have you run the ECU output checks? (see SJM's website:
http://www.SJMAutoTechnik.COM/ecuf20v.html#out3), These produce an
audible electrical test of various solenoidal functions--including
each injector, carbon freq. valve, and wastegate freq. valve. Also
there is a resistance spec. in Bentley for the wastegate freq. valve.
Sounds like perhaps your WGFV is defective.
