Educate me: during up or downshifts and letting off the gas, I should hear the BOV, right? Or only at certain RPMs? Sure as hell looks like its installed properly to me, I mean come on, a DCX mechanic should know it can only install just one way.

It is not the RPMs that effect the BOV it is the pressure behind it. They open when the pressure spikes and then release the pressure rather than backing up the turbo. If you are tooling along at 35MPH and let out of it, it probably will not open as the turbo is not boosting. But if you get out if it after a full throtle pass, the turbo is under full boost and will spike the pressure and pop open the BOV. They work much like a waste gate but you cant adjust the pressure it opens at.
