which is whats what you want since the controller is reading that pressure and adjusting the solenoid based on that pressure. If you have an imbalance of one side producing more or less boost and only have that pressure signal hooked up to one side then your gonna have problems that will be difficult to track down. You could even grenade the motor or a turbo if the sensor reading is coming from a side with a boost leak and getting no pressure but the other side goes beyond the intended psi. Now for the pressure signal going through the solenoid and to the wastegates, the source of that signal coming from a single or tee'd line may not be so critical. Im getting that signal on my Greddy E-01 from a single port off the back of the plenum.
