I know my diverter valve is bad from my recent trip to the dealer. It was sticking and not building boost. The tech tapped the side of it with a screw driver and freed it up and has been working ever since. I know these valves go bad in a short time and my is the original valve on a 2000 1.8T. I want to replace the valve with an up-grade or one of these nice billet pieces I see. Who has the best valve out there and can I use one of the valaves that bumps the boost into the atmoshere rather then using one of the closed system valves with a 2000? I know this is juvenile at 45 years old, but I really like the "Woowsh" sound an open valve makes.
