Has anyone else had this problem? When the key is first turned to the on position, a chirp or high pressure squeek can be heard that sounds like it is coming from the air filter. It also happens at low speed when I get out of the throttle. I have and airaid setup and a Razors Edge smooth intake tube. Any advice?

 

Fuel pressure noise in the injector rails? Mine does that sometimes, but it is a very high pitched, soft whine that happens after a wot run.

 

Try jiggling (technical term) the Airraid box, and see if it has any squeak to it.

My JL Ram Air setup squeaked for a bit then fixed it... actually my dealer fixed it
