I think my car has a slight boost leak, today on my way home from work it made a weird noise a few times and I looked up the sound of boost leak and that?s what it sounds like. Like a weird fluttering noise at the end of the gear in slightly higher rpm?s. It only made the noise a few times when I was in sixth getting into it on the freeway and in fourth getting into it on a street. Other than that my car still feels like it has good power what els could it be and should I take it to a tuner/mechanic to check it for me?
