Ive been running a stock procharger bypass valve which has always made a fluttering sound, but im quite sure its just how it sounds and not surge.

Anyways, im sure I should probably ugprade running the amount of boost I do and being intercooled but im more concerned with it leaking boost.

Does anyone have actual experience picking up boost when switching from an OEM leaky bypass to a better race bypass?

Im sure mine leaks some but I just dont see it being enough to cause any significant amount of boost loss.

anything over 11psi, they will leak a little boost

Im assuming it came with a procharger kit a while ago.

I have a bosch one laying around, but I dk if it would be worse or better than what im running.

This one im running is like a straight metal tube with a tb like flap.

Not really sure what it is otherwise

i'm using the pro flow by pass valve and i had it at around 9-10 lbs last year and it held. i had the one you have on an 11 lb set up awhile back. didn't work that well lol.

It's worth the swap just for the awesome sound a race valve makes, not to mention the performance

Pick up an enclosed Procharger race valve, and trade me.
