What's the bov mod accomplish?


From what I've read it helps the BPV hold higher boost pressures at the cost of disabling the over-boost protection. I have boost cut so I'm not worried. I've noticed that it only opens when I shift after building peak boost or its a whole lot less noticeable compared to an unmodified one which opened at the slightest amount of boost when shifting. I've had people confuse my BPV for a BOV in my previous car.

BOV is not an option. I'm not a fan of the noise they make.
