ok felas, when my sc is idling its fine

when i give it gas to move its fine but hen i let off throttle it whistles....what the hell is going on haha

its freakin anoying

just when i let off throttle tho
 
I think I have this as well. In mine it's not a loud whistle...and I can't notice it unless the music is off. I think mine only does it when I apply the brake and come to a complete stop. I don't know if this is the same whistle thing, but I had been wondering what it is for awhile now.
 
My best guess is somewhere around the bypass valve? maybe a leak at a vaccum hose or the gasket. Sounds to me like your getting the sound when you suddenly get vacuum, (deceleration) kinda like the opposite of a BOV. Im not an expert by any means, but this is my .02 Good luck :)
