Hey Diego, I'm glad you are enjoying the car! Can't wait to hear more about it!

The BOV will make the car run rich on decel. As you mention, because we use a draw through setup the car's ECU has measured and is therefore expecting the air to be entering the engine. However, as the air is not there it will run rich.
With that being said, we've been running blow off valves on draw through MAF vehicles for over 20 years. I've only seen it cause an issue when the BOV isn't set correctly and is overly sensitive and if you're cruising slowly through a parking lot or something. It could open and cause the car to stumble and possibly stall...again this only occurs at low speed. But we've been running these dual pass BOV's on our GT R builds and as Diego pointed out, our Z currently has this BOV on it as we continue with some more testing.
Also, just to clarify, the shields in Diego's kit have been in all of the G kits since we began production. The Z uses a different shield but it too has been in there since we began production. These shields protect the intake/filters but also help to clean-up the air flow before the air enters the intake path.
