Yes but it depends.

Where is the BOV. If it is a C2 style blow through conversion the BOV is usually before the AFM and no effect.

If it is a 993 based conversion it should be converted to a suck through to protect the MAS wire. So the BOV should be after the metering function. However, these cars have TPS, when the TPS signal's low throttle angle at an elevated RPM fuel it usually cuts back fuel based on the cell value.

With a stand alone EFI, most turbo's are MAP sensing after the throttle body so the BOV is not going to be able to be located where it can effect AFR's. However, fuel can be programed where ever or how ever you want it.

On an MFI or CIS car the popping and flames are kind of part of the ambiance. Doing this on an EFI car for the effect is as the potential expense of premature turbo ware.
