Nice part, installation is easy, just make sure the port is aligned with the one on the compressor housing. Sounds basically the same as the stock one as you should expect.

Please note that if your tuning plans call for boost above 15-18 psi that you might hear a fluttering sound--this is the valve leaking. This is harmless, but a shim on the included spring or a slightly firmer spring will solve it if it bothers you or if you're losing too much pressure. Forge makes both of those but doesn't bother including them.
