|   Not Ranked : 0 score  Just check the actuator action with a regulated air source. It should not move before 11 psi, and begin slowly opening as you raise pressure. Mine does not fully extend the rod until about 17-18 psi. Don't use a pressure source higher than 30 psi or you could blow the diaphragm in the actuator. The advice above seems sound regarding actuator and EBC. You can remove the actuator without removing the entire turbo, but it is a bitch and not really necessary for testing. If you remove the rod end from the wastegate flapper, the flapper should move freely. If it does not, that could be your problem if it is not opening enough when commanded. Another thing to do is get some soft wire and wire the actuator rod shut in place so it can't move. Boost should hold at 11 psi. You are correct that max rod movement is less than 1/2". I'd be looking for a hair split on the tubing going to and from the EBC. Replacing those lines is cheap.
