    Strange Dump Valve Sound

    Bear with me please as I don't know much about turbo cars.
    I have a B2 90q with 3B engine, it has a notable dump valve when letting off the accelerator, when I took it out today the sound is completely different from normal, when it is releasing pressure it flutters like what you hear on rally cars. It sounds really cool but it has never sounded like this before.
    Any ideas what may be causing this?

    Check the hose from intake to dump. Its probably broken somewhere. My guess is at the dumpvalve because of the 180 degre bend...
