I've recently had an Revo Induction Kit fitted to my Audi S3 8p, But Since Having This Done My Turbo Has Started Fluttering And Have Read That This Can Damage My Turbo, What Is Best To Stop This From Happening As Don't Want To Be Funding A New Turbo, Heard Blow Off Valves Can Stop This But Heard This Can Effect The Performance Of The Car Is This True? Any Information Is Much Appreciated.
