I was just talking to Nate myself about the vacuum lines on the factory boost solenoid. What Shiv was asking about was, did you keep your stock vacuum boost lines, or did you put the ones from the VF34 on? Shiv has found that on a US WRX, it's better to keep the original stock lines. At this point though, I'd bet you have a knock prone car, or a hypochondriac car.
