Get a good schrader valve (I typically use an old valve from a bike tire). use a hose clamp and some length of vacuum lines and a vacuum 'T'.
Put the schrader valve on one port on the T, and a vac gauge on the other.
now you can test in a couple ways. find a part in the vacuum tree you want to test (like the FPR). now plug the last end of the T into that line, removing it from the vacuum tree. use a compressor or perhaps a bike pump and set it for 20-30psi... you should be able to hear the vac leak, if not try spraying soapy water and look for the bubbles.
the other method is to plug your intake with a pipe plug and to pressurize the entire intake. you can do it before the turbo or at the throttle body to test different parts.
make sure you dont bypass the vac check valves, it could damage some components meant not to see boost.
