My turbo does not have a pressure source nipple. how would i go about plumping the vacuum lines on my AEM try boost mac solenoid?

Intake manifold and wastegate should be reference points..

 

okay so in figure 7, since i don't have a nipple source on my turbo i should get the vacuum off the manifold?

figure 7 is about mid way.

 

Intake manifold.. yes

 

I just drilled into the side of my turbo and fitted nipple.

 

some do that. In my experience, especially when using a very efficient airflow wheel, the compressor nipple is actually too strong of a reference point that causes boost creep issues when the tuner is using the solenoid to target wastegate spring boost levels.

I've never used the compressor housing (even if nipple is available, I plug it up).
But there has been a whole contorted debate about the whole thing I refuse to into because of its redundancy.
