It?s making a weird fluttering/whistle when I?m getting into it I don?t know if it?s my waste gate, compression surge, boost leak; or all of the above ??*?? I?m taking it to a tuner this next week and have them check it out for me and tune the car for the el headers I just put on it.. I feel like after installing the equal length headers I lost a little power.. probably because I need a tune now right? And I?m sure that noise I?m hearing doesn?t help either
