So your saying the electronic stock BOV is better?

Performance wise vs. A VTA set up, yes. The system was designed to vent internally, so removing that air from the system can cause some loss of performance. Some people really dig the sound, so if it's wort it to you .... .
There are companies that make internal venting BOV. Go Fast Bits (GFB), make an adjustable BOV so you can vary the amount of air vented to atmosphere. Kind of the best of both worlds. I don't know if they make an application for the Raptor. Just some stuff I learned from the import scene.
