You're talking about many different things here. We'll start with venting. Venting is a very bad idea if you are running the stock 2g maf. The air that you are venting to the atmosphere has already been accounted for, therefore you will have extra gas used in the engine. Vening will make your car run like arse and get very bad mpg. You can vent safely with something like the gm maft, where the bov is before the gm maf so the air hasn't be accounted for yet.
Compressor surge is when you are under boost, you let off the throttle, the throttle plate closes and that pressure in the pipe has to go somewhere. The bov is there to detected the throttle plate closely, and let the pressure escape from the upper ic pipe back into the intake of the turbo. If your bov is not functioning properly, it will stay closed and not release this pressure, so the pressure wave finds it's way back to the turbo, causing compressor surge.
So venting and compressor surge or not really related to each other, or venting is not a fix for compressor surge. If you are getting compressor surge, then maybe your bov is too tight and not releasing the air. Do you have an adjustable one like a greddy type s with a nut on top of it?
