To cut a long story short, The surge you get back through the turbo is caused by the bov opening being too restrictive either by the opening too small or the BOV not responding quick enough. True compressor surge only happens at wide open throttle NOT off throttle and has a way louder aggressive note.
The surge you are experiancing is nothing to worry about and wont damage you're turbo, this is what people in the know have told me on this forum.
I too get surge back through the compressor until my bov responds and vents, thats with a 50mm bov and dedicated line aswell, but meh its been fine and ive had no trouble...

And my mate actually got better response by HARDENING his HKS bov, weird.
Sounds like you have got a "Toyspeed Anomaly". Try a different bov, hard for anyone to recommend one as they all seem to work differently on different peoples cars
When I had the faulty SSQ, it kinda sounded like a whip being cracked, with the chachacha after, and was very loud also!. With the 50mm one now, I only get a brief cha, then bov vents. Thats on 19psi aswell.cat007 wrote: Of course its a different tone to the engine/exhaust - but still - VERY loud....
