Also, since you're running an internally gated system, make sure you have hose clamps on the actuator feed hose.

Underboost it can cause a boost leak if not clamped causing the arm to close the wastegate door and thus increasing the boost.

Simple fix....

Okay, I finished up re-tensioning the arm. OH, AND, i did it with the turbo on the car.. and it took no time.. I'm so talented. Thanks for chiming in MDC, I am running clamps on the hose, and i've pressure checked them. I havn't taken the car out for a spin yet, but I'm not having a good feeling about it. I barely loosened the arm at all. If this doesn't help, I'm going start to grind down at the flange of the downpipe near the actuator door, I dont think its the culprit, considering with the new wastegate there is no more creep.. just a steady 21 PSI. I just want to make sure. We'll see tomorrow.
