    i had a similar problem with my 3s. it was one of these two problems:
    the boost line going from the comp housing to the wastegate actuator was quite long and it was pinching itself, blocking the air.
    or it was leaking because it wasnt clamped/tied.

    whats your vacc reading sitting at idle?

    Have you checked that you have set the EBC up correctly? Sounds to me like it isn't actually using the EBC and is on wastegate boost levels.
