if it were running a MAP or MAF system, that would be another story, as those sensors are after the turbo, and can vent to the atmosphere while still receiving the correct air volume signal.
if you get a recirculating system for your BOV, it would be possible to run it, but pretty pointless, as the system is designed to work without one.
someone else more versed with turbo apps can prolly shed more light, but this is my .02.

That's partially true. The 7MGTE runs a BPV in place of a BOV, so excess pressure is already being rerouted into the intake system (after the KVAFM). I would suggest upgrading the OEM valve though as it is likely original (20+ years old). Also, many aftermarket valves are less likely to leak boost pressure prior to opening the valve
