how to adjust your wastegate actuator ?
my wastegate is not closing as fast as it should so when i shift with boost i have to wait a few seconds for it to close. i want to speed it up.

How do you know it is the wastegate not closing?
It might be normal. It takes a moment to build boost up again, maybe longer with sequential quirks at certain RPMs. It might be wastegate cracks that always bleed off a little exhaust energy. I replaced my old, cracked stock twins with a newer set at one point and got noticably better boost reponse afterward.
I think you have jumped to a conclusion about the cause of the issue that may not be correct. There is really no adjustment, per se, to change the rate at which the wastegate closes after a shift.

1. Clearing your mind of the idea that the wastegate is closing too slowly. That isn't the problem.
2. Describe what you are doing and how the car responds more clearly so that someone can help you.
