Just like Grimace, I too hear a whistle at low RPMs coming from my STEEDA CAI. Sounds kind of like a faint dog whistle. Its inconsistent when it occurs exactly and how long it lasts, but it is definitely only at like 1500 RPM. Like, when you're at a stop light and start to go. After a couple seconds though, its quiet.

At least in know I'm not crazy now! Maybe I'll give the filter a jiggle and see if it gets rid of it?
