The flapper valve should be closed. As you shorten the length of the threaded actuator rod you increase the force of the spring pulling the flapper valve shut down onto its seat. Adjust it to where it slides on and off freely. THEN, rotate it in three more complete 360 degree turns. This shortens the rod and pulls the valve down onto the seat harder which will improve spool up of the turbo.

The turbo was already installed on the car. I just thought that the waste gate may have had some error when installing so I just left it there and have not started the car.

Then look at the threaded actuator rod. On the end of the rod is this piece that we'll call the turnbuckle. There is a flat on the turnbuckle with a hole in it. Loosen the backup nut and adjust the turnbuckle so that the hole is positioned erectly over the peg on the end of the flapper valve's pivot arm. Slide the hole in the turnbuckle up onto the pivot arm peg.

Now, remove the turnbuckle again away from the pivot arm. Rotate the turnbuckle inward which effectively shortens the overall length of the threaded actuator rod. Now, pull the turnbuckle/actuator rod assembly back up onto the flapper valve pivot arm's peg. This time since you've just shortened the overall length of the actuator rod you will need a bit more stregth to pull the turnbuckle up onto the peg.
This. Very well said

Well i took it apart and then figured out that I installed it correctly the first time. However I'm glad i double checked... wanted to be sure I didn't blow the turbo. I started the car and it runs well. thanks guys!
