Leak tests,,,,
Option 1, remove air snorkle and seal off turbo intake. On compressor outlet elbow connect a vaccum pump and pump away and it should hold vaccum. If not you have a leak.
Option 2, pinpoint leak by idleing the car and using a small section of vaccum hose. One end goes by your ear, the other end goes around throttle body areas you believe to be leaking. The sound will be different where there is a leak and where there is not.
Option 3, Take off air snorkle and seal it off. Add regulated pressure (about 15psi) from an air compressor and see if it is leaking anywhere.
Option 2 is the easiest, and allows you to pinpoint it.
