To answer your question, no there's no issues on this car due to the location of the bpv and the lack of a maf sensor. The bpv is so far back from the turbo that any small amount of air it recirculates is negligible. The lack of a maf sensor means the computer is reading air velocity, manifold pressure, airflow, etc from the intake manifold (MAP sensor). Therefore the bpv venting to atmosphere should have zero negative effects on this car.
When you take your foot off the throttle, the throttle body closes and the air in all of your intake system comes to a stop (because it can;t go into the motor). When all that air stops moving, the turbo charger is still spinning working against that air that has stopped and that hurts turbo parts.
That's when your valve comes in to play. When the throttle closes, the valve opens and keeps the air moving. For us, the air can go anywhere. Back into the intake, out into the engine bay, through a tube down to the ground, literally anywhere! It doesn't matter as long as it is un-restricted and moving!
All of our engine's air metering is done in the intake manifold so there are zero side effects to not recirculating the valve air other than hearing the valve open.
