n00b question here, however. wouldnt you want the BOV's after the intercooler and before the throttle body, or does it really make no difference? i'm very curious about this.

The purpose of the BoV is to prevent the throttle plate from closing and causing air to surge back through the compressor blades on the turbo. Having it closer to the compressor outlet allows it to vent air from the intercooler core and retain air in the piping between the intercooler and throttle plate. This means that the compressor has less piping to fill when the car is back in boost, meaning slightly better boost response between shifts.
That's the theory, at least......

thats a very interesting explanation craig, thanks for clearing that up with me.
the way i had pictured it in my mind, it seemed most logical ( to me at least) for the BOV to be closer to the throttle butterfly. this way, when the butterfly closes, the charged air has a quick path of escape through the BOV, since it would be so close. however, after thinking about it for a minute or so, your explanation makes more sense

I would definitely rather have a turbo that lasts 20k miles more than slightly better throttle response. That's why NLTS was invented!

Once the throttle plate is closed pressure doesen't necessairly reverse direction, however it could stay dormant.

i actually run two BOVs before the turbo on the intake pipes, two on the intercooler on the very top of it, two on the intake manifold, two on the boost solenoid, two on the muffler and two on the rear two injectors...
i get the best throttle response, best injector firing, best intercooler safety ( big in my book ) best turbo intake safety and of course, i can spool up at full boost by 1250 rpms....
