I swapped out my crappy stocker for an MR BOV last night, and during the process found that the hose clamps holding the stocker in were loose about 3/4 of a turn. Anyway, I swapped out the BOV and gained back 1.5psi I had lost, and gained back idle vacuum that had gone missing. So besides the fact that the MR BOV will hold more boost than the stocker and generally seals better, I would recommend everyone go out and check the hose clamps on their BOV's - and make sure they're tight.

Cheers
