    Question Loss of boost???

    Hey everyone I am new here I just need help ASAP. So I installed a Cobb SF intake I also have a spt exhaust and a Perrin BOV my problem is i was running around 15-17 PSI and all of a sudden I have what i believe is turbo lag and now i am only running around 7-9 PSI WOT so if anyone can please help me figure this out im not sure if my boost gauge is off or not but im also in the high 6 to low 7 sec 0-60 now. The people i take it to here are useless and the guy that installed my parts is also useless so if you have any idea of whats going on even if your not sure but think you know please let me know thanks.

    Did you check for a boost leak?
    The world breaks everyone and afterward many are strong in the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry. Ernest Hemingway, A Farewell to Arms, 1929

    Verify your BCS is still working properly. If you put the car into "test mode" (like you were flashing the car), you should hear it clicking.

    I bet the new BOV is leaking, your search for the cool PSSSSTTTT is the problem. Take it off and try with the stock to see what happens.
