Re: vacuum lines for boost solenoid
The one that has pressure from the compressor?
It opens the wastegate. Without it, your boost will be high. Very high. As in gasket-poppin' high. Basically, without any control at all. Of course you'll lose a bit of pressure via the open fitting or loose hose. But there is not enough volume there to really keep things in control.
A straight piece of 7/32" hose to replace it will work fine.
