Ive got a greddy Type S on there. Before the car sat for three months, it sounded fine. Now that its back running, you dont hear that pshh sound from it, the best way to describe is it sounds like Dr. Zoidburg from Futurama. We have a 3.5mm line running from the back of the uim to the top of the bov. Does anyone see a problem with this set up?

 

That sounds right. Perhaps your BOV is sticking. How does your boost look? Spring tension?
