newbie question here.. what is the purpose or benifits of running 2 bov's?

 

If your turbo(s) is moving more air than 1 valve can bleed off quickly enough.

 

Check out Synapse's videos on youtube...slow bov's require a lot of size since they react slower and after boost starts to spike. They have a very small valve that can handle a huge system because it reacts within milliseconds. It's cute
