Wastegate/Boost controller vacuum routing. Who is right; Tial or GReddy?
The installation diagrams are different from eachother. I have a Tial 38mm and a Profec B. Which diagram should I be using?

If you are using the Spec II I believe it is COM port to the top port on the wastegate, NC port to a good pressure source (intake manifold or turbo compressor housing), side port on the wastegate to pressure source.

With the exception of the "vent", the diagrams are the same.
Just make sure you're using the correct solenoid ports for an external wastegate and that they go to the correct places. >

Can that be the vaccum line from fpr to the intake manifold or the brake booster?

Dude, the diagrams essentially show the same thing, the boost controller supplies pressure to the top port of the wastegate. The Greddy unit vents inside the solenoid/stepper motor box, so they don't show the vent on their diagram. Just run a line from your intake to the Greddy valve box and from the box to the top port of the gate.
