Synchronic + Truboost Connections
Just like to say that I've searched and couldn't find a clear answer on these forums, so hopefully someone can help me out before I make any mistakes
So plumbing the lines, as I understand it should be this:
Wastegate and Turbo outlet (MM fix #2) plug into AEM truboost solenoid (into ports 2 and 3 according to manual) and port 3 has a sintered muffler.
BOV Connections: Using the Vaccum line from behind the throttle body, use a T-fitting, where one line goes to the AEM boost controller gauge, and the other goes to the BOV - where again, it is T-fitted to cover the dual inputs that synchronic uses.
Now on to my question regarding boost only source... I was going to simply take the sintered muffler from port 3 on the solenoid off, and attach a line to the boost only source. Is this okay? I was having second thoughts as it was briefly mentioned in one of Synapses video's for stock vehicles that you should not connect the boost only line after a solenoid connection, and I wasn't entirely sure why.
... If this is the case, should I just attach another T-line from the turbo outlet (fix #2) to the boost only input of the BOV leave the sintered filter?
Sorry if this seems basic, I just want to be sure! thanks in advance

Don't overdo it with the T fittings, it can weaken the air signals you are providing.
Drill and tap the intercooler piping if you need a boost only source. Buy a 1/8 NPT tap and 11/32" drill bit for it. Thread in a 1/8 NPT --> 1/4" barb fitting from the hardware store. When you thread the fitting in, put a little RTV on the threads so you don't get a boost leak (skip the teflon tape, that stuff is a pain).
The muffled side of the AEM solenoid should not be used as a source for anything. Either keep the muffler on or take it off and route it pre turbo. Air only flows through that muffled side when the solenoid is energized. The boost controller rapidly cycles the solenoid on and off depending on how it is tuned.
