Update
so today i went searching for a plug to close my greddy bov and had no luck so after some mcgeiver thinking i cut a section from a soda can and placed it between my bov and the flange started the car and let it warm up, sprayed some carb cleaner in the bov hole no change of idle perfect no leaks, i rev the engine and no more stalls! so i take it out for a drive and same no more stalling i do get some occasional black smoke from the tailpipe when at a stop after a wot run (i think its running pretty rich) so now it looks like im going to need another bov correct? what are my options, im leaning more towards hks and not recirculating it
just want to say big thanks to kane & jeff and everyone else for all the help!

on second thought...wouldn't the anti-stall fitting work fine without switching BOV's? it's way cheaper too....plus if i'm not mistaken you will have to get a different adapter welded in to fit the HKS or other bov

That doesn't test much that is relevant to this situation.
What you need to test (and can't easily) is the opening differential.
A BOV is opened by a combination of pressure and vacuum.
Its that balance that determines the effectiveness of the device.
The GReddy is modulated by the pre-tension on the spring.
The HKS has a fixed ratio of vacuum to pressure at which it will open.

Looks like I'm running the exact same setup as gregs. While I had an idle problem originally, it sounds like gregs' is much worse. However I found that it just took a lot of tweeking on the RS bov to get it to play nice. There seems to be a very small range where it won't stall and will still discharge enough of the pressure to keep the turbo from spinning backwards. Just a thought.

well i finally installed my hks bov today and didnt have to cut and weld a new flange i found a place that sells a adapter like MM said and works just like it used too now...what a relief! once again thank you to everyone that has helped me through the whole process, i will post some newer pictures sometime this week, and get some videos up soon as well!
