I installed a mac solenoid in my fd. I'm having a problem with boost dropping after 6500 rpm. Any suggestions to cure that? Probably going to end up getting a boost controller but wanted opinions. No pills in the lines. It's set at 11 psi and wastegate is ported. Car is non sequential. Thanks.

Wiring Diagram
I will be installing both Mac solenoids shortly to control my BNR Twins. Now that you all have clearly explained the vaccum routing how about a wiring diagram.
Thanks

Sorry for bringing up this old thread. I just replaced my WG solenoid with a MAC valve. The transition was quicker and the boost more stable.
Red and yellow in the graph are stock WG solenoid and green is the MAC valve.
I think I will replace the PC solenoid as well.
