Vaccum Line Routing
 

Is this setup ok? Line from intake manifold goes to a T which then goes to BOV and manual boost controller which then goes to the wastegate. I ask because seems as soon as my WG opens (15psi spring) the car almost like looses all power. Not RPM/gear/throttle specific.

Thanks.

Ideally it's best to have a direct line off the compressor housing to the boost controller and then to the wastegate. Tee'ing it with other things delays the signal.

My stealth seems to boost spike more since I moved the wastegate/boost controller source to the engine side of the throttle body. Factor location is the instake side. My Talon uses the source right off the turbo compressor housing.
