boost bypass

[Erik Adam Rodriguez]

when my bbv is connected to the solenoid i only get 3 psi of boost, then i undo the vacuum line going from the bbv to the solenoid i get 7 to 8 psi. , is the solenoid bad or the bbv?

The lean bank one is something else. Often vacuum line related

Which means you need to check all the rubber "T" fittings and plastic vac lines around the blower/LIM/TB/MAP/FPR, etc.
