Please help me with the installation.
I tried to ask for help on another post, but couldn't get enough views so here is a new thread.

First of all, I don't know much about vacuum lines and boost lines so please bare with me.

According to the installation guide,
A and B is supposed to go to vacuum and C to Boost only source

So here is my guess.
line 2 is line going from existing bov to vacuum + boost controller.
line 1 is going from boost controller to wastegate. (I think)

In the pictures, I would think A and B goes to green line at (2) and C would go to red line at (1). right?

Please let me know if I am on the right track.

 

Ports A & B are supposed to be connected to the intake manifold and Port C is supposed to be connected to the turbo compressor housing. Thats it! The only other variables are whether you want to run A only, B only or both. Don't cap the nipples if you run them individually either. Let them vent. Personally I've found the best success running B only (and C of course).

My only complaint with this BOV is that it seems to suck holding boost at partial throttle. Like if you boost to 15 psi and want to hold it there, after a few seconds the Synapse just blows off ON ITS OWN (as in, I haven't released the throttle yet) and starts to flutter like crazy. Sounds almost like an angry turkey! I don't know if adjusting the pre-load screw will make a difference with that but according to the manual you're supposed to leave it as loose as possible? Maybe Synapse has a solution for this?

 

I wasn't aware that there is a place to connect a line on the turbo compressor housing.

That is a different line then the red line in the picture right?

 

Sorry, the line actually connects to the nipple on the turbo outlet pipe aka the J Pipe.
