Does anyone know how much psi the stock SR recirc valve(s14) will hold? I am trying to adjust my PRofec, and I can't seem to get mor than .5/.6 Kpa...I am looking to run around .8...

I think the spring is too weak, what you have to do is knock in the top of the valve to increase the spring tension which will hold a little more boost. That's how the DSM's take care of theirs.

On stock turbo the stock bypass valve should be holding 14 psi easy. I did it for 2 yrs and never leaked on me once.
