This leads to a rich mixture.
This makes your mpg lower.
Your cat coverters run hotter, longer.
So, by adding a little bling to your ride, it now runs like a Yugo on three cylinders.

PPSsssssshhhhhhh!!! MOBY!!!!!

I hear there is a mod you can do to the stock bov to allow you to use it with higher psi +20.
I'm running the WORX bov and some times I run it 100% recirc and some times I open it up 50 to 100% just for the noise factor. It works for my setup the way it should but it's pretty much just a noise maker.
