Here is the deal.

Had my car tuned by Bill (a.k.a. skywalker) from I-speed and we had some problem with keeping the boost down from 18psi at 5800 to 6500.

Tried screwing out the wastegate and I helped a bit.

Now I am hearing a rattle from under the hood. Found out that when I rev the motor it rattle the wastegate.

Will this hurt the wastegate?
Can I put a washer under the clip that holds the diaphram arm to the wastegate, between the clip and the arm?

Just trying to get ride of the problem if I can, because it make the car sound cheap.
