Default Blow Off Valve Recirculation - The reasons why all happy turbo cars should!

heres the answer straight from the horses mouth, for those of you, like me, that are currently running a JWT program. this is in response to my email to Ben from JWT.

Hi Jay,
The Nissan control system was not designed to run a BOV to
atmosphere. There is no way to make the ECU work with this as the
amount of air flow in the system that is lost if an atmospheric BOV
opens is an unknown amount to the ECU. Once the air flow comes
across the MAF sensor, the ECU expects all that air to be in the
system and adds the fuel based on this amount. So if you do not want
to have the stalling when coming to a fast stop and/or the rich
conditions between shifts, we recommend you run a recirculation type
valve (also known as a compressor bypass valve). It might be
possible to convert your existing valve to the proper type. Check
with the company that made your BOV for this. Note that the air flow
when recirculated, should dump back to the inlet side of the turbo
and ideally aim at the compressor wheel in the turbo inlet. This
also helps keep the turbo more responsive between shifts.

Best regards,

Absolute truth. I would love to have an SSQV, but that'll never happen unless I use a recirculation kit... which sort of defeats the purpose until I'm making more boost than the stock BPV can hold.
