Educate me on BOV vs BPV

Does turbo response suffer when you switch from BPV to BOV. I know in my Speed (even though that was MAF) made a pretty noticeable difference when I vented.
No, there will be better throttle response and turbo recovery during shifts.
Hey all,

I'm interested in possibly getting some sort of BOV for my VN, but I don't really understand enough about the types or benefits/drawbacks to make an informed decision at this point.

I know that defeating the factory recirc valve will void the warranty, but what I'm not sure of is will a BOV harm operation or reliability of the car in any way? Could there be any potential issue from installing a BOV on this platform, such as the engine running too rich due to MAF sensor readings?

I'm considering installing a BOV of some sort because I like the turbo sounds, but there are so many different types on the market that it's a little overwhelming...
This will clarify the differences;
