Leave it alone if you don't know what it does. Lol.

When you bolt it up, you will understand what it does

Allows you to adjust the tension on the spring that holds it closed under boost pressure.

I run stock boost, what I did on mine was loosen it in increments until it doesn't hold stock boost and then tighten it in small increments (either 1/2 turns or full turns) until it does. This will ensure that it is not to tight but tight enough to hold under boost.
