Hi guys, this is my first post here. I actually don't have an Audi, I am driving a s197 Mustang with a Vortech supercharger. I am planning to run 15psi on the supercharger, and the Bosch bypass valve will not work with that much boost. I am looking at the Hyperboost HXc bypass valve, but I cant find much info in the Mustang world. Will the HXc work with that much boost? What is the maximum that you guys are running them at? Also, how are they in quality? Are they stable?

Thanks guys!
