You have a boost leak. Check your hoses, couplers, vacuum lines, for leaks. The most obvious cause is the couplers for the intercooler pipes. Actually take them off and carefully search for splits.

Do you hear air venting when driving the car?

check your solenoids as well..
you wont generate good secondary boost until you exceed 7psi on the primaries..
