2G Boost Control system?

So I was looking into my car and checking things out, just to make sure everything is connected etc. and I remember about the free boost mod and i wanted to check and see if it was done to mine. I found the waste gate solenoid hanging down unattached to anything with no lines going to either nipple. Pics below
I also found this other "thing" up against the firewall on the driver side with a adjustment thing. Is this some type of boost controller? Also my intercooler piping right past the turbo output has a sensor wired into it. What is all of this exactly. I tried to search it but i honestly have no idea where to start, or what to call it, or anything. Thanks in advance for the help

Let's take this to Pm's instead of cluttering up this thread. But no I won't be able to make. I'm installing lots of parts, so car is stripped down under the hood.
