So I picked up an ER chargepipe from N54tuning. Mike really lives up to his reputation of amazing customer service.
Anyway, I took my HKS BOV off the UR chargepipe it was initially on. Reused the retainer clip and O ring to install it on the ER chargepipe. Everything works fine except the fact that the BOV can rotate freely without much force. It was tight solid on the UR chargepipe. I already talked to Mike and he suspects a fake BOV or a bad retainer clip. Any other ideas on what it could be? Car is running fine and its holding boost all the way to 15.8psi. Im just not sure if air may be escaping from the BOV. Any advice would be greatly appreciated. Thanks in advance!
