boost leak isolation?
based on recent VAG-COM logs I've determined I have a boost leak - actual boost is 300 mbar+ below requested, and N75 duty cycle is pegged at 95%. What's the best way to determine the location of the leak? I've looked at the various hoses and haven't seen anything wrong, even swapped in a different DV. Suggestions?

I can hear some air, but it's not like the last one I had
the last one I had was a tear in the vacuum line that runs parallel to the intake manifold, and you heard a huge whoosh when boosting. With this one I can hear some air leaking, but it's not nearly as loud. Performance is suffering, and it's laggy as hell.

3 ways
1) Spray a soapy water solution on the hoses and fittings and look for bubbles.
2) The make tools where a smoke is injected into the system and you look for leaks. (this was done to my fuel system)
3) They make listening devices. Poor man's version is a hose to help direct your listening. This one works on vaccum leaks where 1 and 2 only work on positive pressure leaks.
