Which Blow off valve is recommended to use on an RB25DET running around 12-18psi of boost?

I have been really thinking about going with a Recalculating Valve. (Like the stock one)Some thing like the HKS Racing Bypass Valve

Until I get some sort of engine management to tune out the car.Then i will most likely go with the Tail bov

When ever you put an atmospheric Blow off valve such as the SSQV or Blitz DD The car will idle weird and some times stall out on you.

The reason is that the computer is programmed for that extra Air.

the point here gents is if you do not have an aftermarket ecu to get rid of the maf. You should recirc the bov so you do not get that stutter. It's not healthy for your ride.
