I would just buy a new one from a decent performance shop.
I had to wait for 90 min for the right one due to my car being on change over year. They got it wrong 3 times!
sorted now but i wish i had saved up and gone for the h.k.s.

a blow-off sends the air flow to the atmosphere instead of back into the intake system, they all do the same job, its just one make a noise there other does not!
a blow-off valve keeps the combustion maintained through the shift, the turbo and the engine keeps their rpm up better, giving a better response after the gear change.

With a "good" blow-off valve, you should notice that you are not applying as much throttle when you re-engage the clutch after the shift. This shows the engine is keeping the rpms up higher through the shift.
although no bhp gain is really seen my response is alot better.

i certainly couldn't in mine,
sum tuners opt to stay with recircs as if you dump air to atmosphere (which has been metered by sensors) then you cud be over-fuelling slightly
