first thing--- loosen the lock nut on the wastegate actuator rod with a 7/16" wrench and adjust the length of the rod so that the tension required to "hook it" back on the rod arm is minimal, meaning very little preload. General guideline two or three half turns is about 1 pound of boost. The longer the rod the lower the boost. Also can you get a pic of the grey plastic y fitting in the vacuum lines that go to the actuator as there is a right and wrong way to run them. You should shoot for 15 pounds of boost to start. hope this helps
