Look at the inner bend of the turbo air intake hose elbow and you'll see the original large vacuum hose capped and tapped with a smaller vacuum hose which I am using to actuate the BOV (in this pict I hadn't yet installed the decel valve)

Are you getting more or less exhaust popping? I never really had any popping prior to the delete, and now I might get a pop or two once in awhile. So I guess maybe just a little more popping but not at all obnoxious.

Do you ever have a problem coming to a stop and the engine dying?(something I heard about from doing this) No issues there. I would think a simple mixture adjustment would remedie that.
I run a small air filter attached to the free end of the decel valve, just as insurance against drawing in any unfiltered air.
