And what did you gain from that?

Just more turbine noise.

I gained more turbine noise, and smoother air flow in that section of the intake. Which was my entire purpose. Any gains in power would be negligible at best. Dodge put that stuff in to restrict noise, because much of the public doesn't want to hear turbo whine. I drive an 18 wheeler, and love the sound.
