I too have a GN, and wanted to ask that same ?? for my on going LS turbo build. Anyway cash is low. Think i will just get the waste gate first, then the BOV if needed.

You don't need one. I'm not running one any more and I'm glad. Caused me all sorts of problems in the past. I'd run one on a manual car for performance reasons but on an auto I'll always run without one.
I'm pretty sure that most turbos can take the stress, everyone thinks they are so fragile.

Most people talking about needing one have read it on the net and you know they can't tell a lie on the Internet! The wastegate dumps boost so why is a blowoff valve necessary? My Duramax that makes 30psi doesn't have a BOV and the turbo has 220k miles it still works great!

im gonna see if this BOV does its job and holds at boost, but if it still causes me greif, then ill be another auto without a BOV lol sill miss the occasional BOV sound though lol sounded pretty cool

I've always used one and never had a issue with it leaking. But I'm building another fairmont and I've decided to try this one without a bov it might be a mistake but I'm going to try it.
