Sound like an ECU issue???

[Cinciguy90Turbo]

I do think it is a boost leak! I'm only getting 5psi of boost max, and when it idles its like 15-16 of vacuum...Idk if this is normal. I have a couple of pictures here I don't know where some of these hoses/valves go. Any help would be awesome nobody wants to work on this car because it's been "chopped up" as they say. But I know everything was perfect before the swap. And I'm pretty sure these things were off before the swap. I bought a Chilton's manual, and its not a lot of help with the turbo setup. Honestly I'm sort of a newbie when it comes to the mechanical. I could tell you specs (hp, torque, 0-60) of any car all day...

There are little read boxes around the specified objects

What is this little guy and where do the hoses go. (I have aftermaket blowoff valve) The openings are not sealed. But I was told that if they were it would blow my headgasket! Scary thought been there done that!


This is open as well it looks important where does it go?


I just want to make sure this setup looks normal...


This "T" off of the MAP sensor and one line goes to the boost gauge (aftermarket) and the other goes nowhere. It is open.
