Boost leak in type 44

[Nick]

Recently i have noticed a significant boost leak in my
Audi 5000 cstq. I have a perfomance chip in it that
usually runsa bout 16 psi. Lately the highest it will
boost is up to 11-12 psi. I have checked as many boost
lines that i could...and all of them were connected
with no real visible signs of tearing or holes. Are
there any common places for boost leak? And if so how
do i test these places. Thanks for the trouble...11
psi instead of 16 makes the car feel like an old
escort compartively.


Thanks again.


Nick
