Fluttering noise after P1SC install

micool · 03-26-2003, 03:35 PM

I recently installed a P1SC Procharger on a 03 GT. The car runs OK but at about 2000 rpms there's a loud fluttering noise coming from underneath the hood. ATI says this is normal and not to worry but it's loud enough to make me get out of the throttle. A few shops have told me to check the bypass or a loose connection. I've never owned a blower car before so I don't know what to expect other than the typical whine. Any help would be greatly appreciated.

could you explain your fluttering noise, is it just the sound of air or something like a belt noise?

Thanks for the concern but today I realized that I wasn't getting the proper amount of vaccum so I plugged into a line coming from the throttle body and the noise disappeared. I appreciate the help!
