Whistling noise--pitch changes with acceleration
2015 Z-51 M7, Original owner, no mods, 8900 miles.
This is the second time the whistle noise occurred.
The pitch rises and falls with the change in accelearation, in gear or in neutral, the whistle is identical.
Anyone else? Suggestions? Reminds me of vacuum leak in my former C3.

Yes, like the whine from a blower. I tightened the big hose clamp around the intake, and no whistle/whine today. Surprised by the number of turns needed to snug it up. Not sure if that "fix" addresses problem because the noise is rare. It is unmistakable.
