rb25 profec b spec 2 problem - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a completely stock series 1 rb25.

For some reason when I try to mess around with the boost controller
the boost doesnt change. It stays around 6 psi only.

I have the greddy profec b spec 2. With the MAC solenoid.

Someone must know!
im only trying to boost 12 psi

I have the vacuum lines connected like this.

Solenoid
#1 port connected to intercooler
#2 port connected to wastegate
#3 blocked off.

I think I put the vacuum lines wrong?
