bov eliminates compressor surge  
this is what i was told, so if its wrong, fell free to correct me

Imagine your throttle plate suddenly closes after boosting. any residual air left slams into the throttle plate, and bounces back into the turbo, creating a chattering noise known as compressor surge. Its the equivalent to bitchslapping your compressor wheel. Its not that dangerous to low CFM turbos, but repeated compressor surge on a High CFM turbo will f\*\*k it up hardcore

edit: i just read n20junkies post, so i guess i was wrong :gotme:
