Much better than just disconnecting the re circulation tube, because it stays closed during light acceleration, so no constant hiss on the highway, but one thing I did notice is a high pitched whine each time after it vents. Hopefully that goes away once it gets lubed up from driving. Don't think I want to live with that whine.

“That is the valve closing and pinching off the air.”
While driving today I couldn’t hear the whistle over the engine, road noise and radio. Guess it’s not a big deal.
