How to: Adjusting the AGP Wastegate Actuator on a 2003-2005 Dodge SRT4/2008-2009 Caliber SRT4

If you’ve bought a AGP Wastegate actuator for your 2003-2005 Dodge SRT4 or 2008-2009 Dodge Caliber SRT4, here are a few quick tips on how to adjust the wastegate actuator after you’ve installed it.

First, for this you’ll need a 7/16 open ended wrench or 11mm open ended wrench. Now, in order to adjust the AGP wastegate you’ll first loosen the locknut which is locking the wastegate arm into place. Then you can make adjustments to the welded nut on the shaft.

We recommend you first rotate the arm with your fingers until you can find where the rod starts to get tight, and the rod is starting to pull the wastegate flap closed. After you reach this point, you can rotate the wastegate arm a little more for more tension.

Now, if you want even more boost than what this setting has given you, you can rotate the arm TOWARDS THE FIREWALL as shown in the photo below.

If you want LESS boost then rotate the arm AWAY from the firewall.
