This may very well be normal, but I dont recall ever hearing it before. Every time i press the throttle in (it does happen if you apply throtle VERY slowly), it makes this blowing noise. I can hear it from inside the car when I press the throttle, its the sound before the actual rev, the blowing noise.

The engine: Ecotec
Mods: AEM CAI

Don't mind my engine bay, yeah its ugly

Any ideas? Is this normal or something i should go have checked out, still under warranty so its not a real problem.

Id put on the stock intake and bring it to the dealer.....Cuz if its underwarrenty u got nothing to loose. Just dont bring it to them with the CAI on it....They might blame it with that, if it has anything to do with the TB or IM.

Thats the sound of the air going through the intake. Its supposed to sound like that.
