There have been about 5 post on the forums about this boost chatter and I have it too on my stage 3 aero. I have heard this on many tuned saabs and my own cars and I really do think its the normal "boost chatter" and its the ecu controlling boost through the bpc and sometimes its just too much boost at low rpm for the head to handle and the bpv will let a little out as the pressure builds up.
I really think its nothing to worry about and with the higher summer temps, the ecu is going to reduce the boost a little anyway and think that is what you are hearing, the bpc controlling boost or letting a little off to keep the engine parameters in check :-)
