What does that whistling sound like to you guys? Coming from gauge or turbo? I feel like it wasn't there before but could be wrong lol....seems to happen after it spools up. The noise other than engine as soon as gauge hits 5 psi ...it didn't used to sound like that...sounds more whistle like...may have to listen real close...any ideas? It's a 2010 RA on 61k miles...did boost leak test, nothing...also swapped the bpv to see if that's bad, still no change...running out of ideas 😑
