[s-cars] Vacuum leak

[Cory Pio]

Alright guys

  Im thinking a vacuum leak might be giving me wastegate/ bpv  
problems. My car pulls about -15 hg in.  When fully warmed up. It used  
to do 20. So my question is my car locking system and the vacuum pump  
under my rear seat a good place to start looking for leaks?

  My symptoms are my car doesn't go into boost right away . The  
wastegate or bpv seems to be staying open unless you really get on it.  
Any help would be much appreciated.

Thank you
