hopefully someone can help me out here... After 36k on the original DV, its about (over) time to change it. Im not noticing huge performance problems, but it does feel a little laggy, and I can hear the turbo hiss much more than on my brothers TT. The questions are: 1. I still have the factory crimp connectors on, I know that these are not reusable, but what are the sizes i need for the vac, boost in, and boost out pipes? Yes i know i'm lazy not to just measure them... 2. Some people replace the vac hose when replacing the DV. Is this really neccessary? Cheers.
