Default Restrictor Pill included

Basically I'm getting boost surging on the Cobb stage 2 OTS tune, which I think I've narrowed down the issue being a missing restrictor least I can't find one anywhere around the turbo.

I've been searching and reading, but I don't believe my vacuum lines are the same as any of the diagrams I've been looking at. From what I can tell, I need a restrictor pill in the line going from the compressor housing to the wastegate. However, the vacuum line from my compressor housing goes to some type of device with 2 other lines coming out of it. I don't know if it's an aftermarket boost controller, or if it's even the stock one...That's what I'm hoping you guys can help with.

I've attached 2 pictures, sorry they aren't the greatest. I can take other if needed.

Here's another shot, in case it helps

I guess my ultimate question is where the heck does the pill go? And am I dealing with aftermarket parts here? Thanks for any help.
