Basically make the waste gate actuator rod shorter. You'll need to pull the rod end off the gate, loosen the locknut, and thread it in. Mine was seized and the actuator rod broke in the end so be careful with it. If you lose the retaining clip hardware stores should have something that fit.

Also, with less boost you'll need to back down on the full load fuel adjust.

Any special reason you want less boost? its not like these motors are a powerhouse in stock form.

I'm having a dumb moment. Making the rod LONGER will decrease boost pressure. Making it shorter will increase it. Had to actually look at the car to remember which way it operates. Make it too long and you get a lot of turbo lag though. Mine was set like that when I got it and the waste gate started to open as soon as the turbo did anything. It made the spool-up take a lot longer than it should have. Returning it to stock boost levels helped quite a bit.
