Help bogging like crazy

So here is the story, I've been bogging for the past week everytime I go under boost. Also, every couple of start ups, the engine starts to stall out and feels like its going to die on me. I know its not hesitation because I fixed it with my Split Second AFC. A couple of weeks ago, my car overheated, cracked the manifold and broke this plastic fitting in a vacuum line that connects to this piece that is screwed into a hard pipe on top. I've been wanting to change that piece but I don't know what the hell it is. I changed the manifold to a SteedSpeed Manifold. I also remapped the AFC but nothing. Everything has been fine since the about a week ago. If any of you guys can help me with the bogging or know anything about that piece, I'd greatly appreciate it.

My mods are: Injen CAI, Corksport FMIC with aluminum pipes, HKS SSQV BOV, Corksport Downpipe, full 2.5" exhaust HKS hi power muffler (no cats), Manual Boost controller set at 10psi, Split Second AFC, SteedSpeed Manifold, Forged Bypass Valve, Garrett Adjustable Wastegate.
