you have to loosen the bottom nut..
it keeps it at the same boost by tightening it down.

yea there are 2 pieces that move, 1 is a locking piece, the other actually adjusts the boost. i don't know what's rattling, try blowing through it and see if anything comes out.

the shaking noise is the ball inside. their is a nut on the bottom threads that you need to loosen b4 adjusting than tighten it when your done adjusting.

Right= more boost
Left= less boost.

i have the same one
