The AAV is buried in the back of an SC but is located more forward and on the passenger's side of a 930. The AAV and decel valve look very much alike. The visual diference is that the AAV has both vac ports on one side while the decel valve has ports on both sides.

I removed these devices from both my SC and 930 with no ill affects. It is reversible but a pain to get to on the SC. I will say that if the AAV was working properly before the turbo addition then you may as well leave it in. Mine were removed to simplify the engine and because the AAR was not working optimally.
