Here's the adjustment procedure less pics.

Boost Bypass Valve
(Picture: L67)

Tools Needed:
1 - 3/8 Drive Ratchet
1 - 3/8 Drive Small Extension
1 - 3/8 Drive 10mm Universal Socket
(Picture: Tools Needed)


Instructions:
Step 1: Locate hood release in driver side foot well. (Picture 1)

Step 2: Pull hood release toward you to pop the hood open. (Picture 2)

Step 3: Open hood by placing your hand between the hood and front bumper cover, making a left to right motion, catching the hood latch. (Picture 3)

Step 4: Raise hood. (Picture 15)

Step 5: Locate the Supercharger Boost Bypass Valve. It is the black cylindrical object to the left of the supercharger, above the front valve cover. (Picture 4 & then picture 5)

Step 6: Move the large set of wires aside from in front of the valve cover. They are held in place by a metal clip that is easily undone. (Picture 6 & then picture 7)

Step 7: Find the first 10mm nut, located just in front of the Bypass Valve, and loosen nut. DO NOT REMOVE! (Picture 8)

Step 8: Find the other two 10mm nuts; they are located BEHIND the Bypass Valve, on the supercharger housing. (Picture 9)

Step 9: Loosen these two 10mm nuts. DO NOT REMOVE! The first nut can be accessed from the left side of the Bypass Valve, the other one is a little trickier, and can be accessed from the right side. (Picture 10 & then pictures 11, and 12)

Step 10: Once all three nuts are loosened, gently apply pressure in a downward motion to the Bypass Valve. You will notice it may move as much as one-half inch. (Picture 13)

Step 11: While pushing down on the Bypass Valve, retighten the three nuts, in the order you loosened them. First the right side, then the left, and then the front. (Pictures 12, 11, 10, then 8)

Step 12: Re-clip the large set of wires back into the metal clip. (Pictures 7 & then 6)

Step 13: Close hood. (Picture 14 & then 15)

Notes:
Essentially what this free mod does is close the Supercharger’s Boost Bypass Valve sooner than set from the factory. This allows the boost to build quicker, this does not give you more boost. Since the Bypass Valve is not robotically set form the factory, it may be placed higher or lower for some, than others. Some people have noticed significant gains from it, and others have experienced nothing at all. I hope you had fun doing this mod, and hopefully you notice something. I had fun writing this, and taking all the new pictures!
