Where to get a boost signal for WG
Where to get a boost signal for WG Do i drill my compressor housing or find a source on the intake? Can I see the same line that my BOV gets its signal from and run it to the WG?
Thank you for the help

I have ran it from my compressor housing and from just in front of the throttle body. I wouldn't use any source after the throttle body as you will have vacuum pulling on the diaphragm. I don't know if that would cause premature wear or not but why chance it. You will see more boost if you source it after the intercooler unless you have no pressure drop across your cooler.
If its referenced pre-intercooler than your wastegate will open early. 8 psi referenced at the turbo and 8 psi referenced at the intake manifold are not the same thing. I only mention it because with all the chinese FMIC's that people run that can have several psi pressure drop, if you want 8 psi at the motor, reference it at the intake.

In case you decide to run a boost controller:
Otherwise, just connect the bottom port of the wastegate to a pressure source before the throttle body (leaving the top port open to the atmosphere).
