I got my car up and running finally, and was out tuning my car with a buddy of mine last night. we did a bunch of runs and then started to tune my car with a little boost. I think we were probably at like .2-.4 bar boost and I was not hearing my BOV open. Is there any way to loosen the setting on it? It sounded like I was having compressor surge when I was leting off the gas.......any suggestions?

You can't adj the tial. They have a softer spring available for it, but it needs a really good vacuum source. Try to put it on it's own source (no t's) and use a big vacuum line (the size on the banjo bolt) and it should work fine.
