The little compressor surge you are hearing, is fine....it will not damage the turbo..It mostly happenes when you release at a pressure so low that the BOV didn't even open....(too low to cause any damage).. many guys run no bov with much bigger turbos, for a few years with no prob, so if you have a stock turbo, dont worry.

I had comp surge for 2 years on the Stock T28(S14), till I upgraded the turbo, and the turbo was in almost perfect condition when I pulled it out.
I boosted about 14-17 psi all the time.
Whenever you do boost hard the majority of the air is released by the BOV so the little surge you hear, actually is very light.
