Hopefully of just what the bov sounds like???

remember, for some strange reasons, the BOV will sound differently on different FDs. Each FD has its own "character" and "personality".

 

ive never heard that before.

a BOV can sound different at different boost levels, but two different cars with the same amount of boost and same BOV should sound the same. boost is boost. that should not change from car to car.
