I was thinking exactly as you stated. The spacer may compensate for the VRAMs behavior to speed the air.
It would be interesting to see what the spacer will do on non VRAM equiped cars.
As I don't have a VRAM intake, I'm thinking the gains could be different than VRAM equiped cars.
Its a bit like filling a wash bucket. With the water nozzle off the hose the water doesn't seem to have much force but fills the bucket much faster than when the nozzle is on and set to jet spray lots of force less water. Ram air is kinda like putting a nozel on the hose and expecting more air, no?

Like jay said, it's about volume and air distribution. The ideal IM pressure would be equal to atmospheric pressure, slowing the air down within the plenum is how you achieve "near atmospheric pressure". The faster air moves, the lower the pressure. But using the velocity from a tuned CAI will help by shoving more air in due to its momentum. The more air that is readily available, the better your throttle response and additionallly the low end TQ.
