Ray,
With 99% probability your wastegate is stuck. Take your cowlings off
and observe the action of the lever arm on the wastegate when you turn
on your master switch. The lever should go through a full cycle of full
on, to full off. I'm guessing you'll see the TCU cable moving, but not
the lever arm on the wastegate. Spray some "Blaster" all over the
wastegate arm and let it soak in. This should free up the stuck lever
arm.

Subject: Europa-List: Turbo problems 914 - Help!!
We have a Europa 914 turbo and are experiencing intermittent high
boosts. So far we have pointed the finger at the wastegate failing to
open and close properly. Could this be the only way this problem could
occur? We have checked that the servo motor is functioning correctly and
also checked all the wiring joints to it. Has anyone else had similar
problems? If so we would welcome any suggestions. - Ray
