Vacuum leak

[GS-T_racer]

this started last week my car only goes up to 10lbs. of boost then stops and I hear air kind of hissing inside the car. This is in every gear at around 5000rpms and it just stops pulling. It has trouble getting to 70mph. Please any help would be appreciated.

Try hooking up a boost leak tester. Instructions on how to make one are at www.vfaq.com and go to intake and scroll down until you see a post for intake leak tester.
