I may have misunderstood you. When you said back to intake I thought you meant after the turbo and intercooler. Since the air is already pressurized and cooled. But you meant maybe back to before the compressor perhaps?

Am I still confused lol.

You would need to vent back to pre-turbo (unpressurized), post-maf to maintain proper metering. Because of the pressure drop through the tract and in particular after the IC, if you tried to route the BOV back to the post-turbo (i.e. pressurized) side, then the BOV may actually flow the wrong way. You need to think of everything in terms of pressures and note that high will always move to low.
