Bogan tuner has car now. Will be tuned with no BOV. If there is an issue he will know and put the pipe with the bov I have in the back seat with him.

on an auto if you dont have a bov it will boost spike and detonate on gear changes.

Boost control with throttle open is the job of the wastegate.

Boost control with throttle closed is the job of the blow off valve.

The boost spike in an auto occurs because the engine rpm drops on the change, but the turbo rpm does not drop as much and the wastegate is sluggish to restore the "balance".

Turbo thrust bearings don't like compressor stalls. AFAIC, people can run without a blowoff valve, but do so at their own risk. Why ruin an expensive turbo when the valve is already fitted std? The loss is more than the gain. Hmmmm.....induce something to fail.....riiight.

They are worth running on a well sorted setup as they will minimise turbo rpm loss between gear changes (and hence maximise boost response).

Not all valves are noisy like the ricer pimp mobiles....:spit:

Simon from NiZpro does not run a blow off valve in his cars and has never had turbo failure as a result of there not being a BOV.

From memory I think he stated a 2 second better time around the track (can't remember which one) without a BOV as the car had little to no lag (not venting all the posotive pressure).

That is good enough for me. I'm now BOVless too and like it.
