Hi guys, just saying hello, bought my first german last week and loving the change. Came from a 2.2 VTI Honda Prelude to a 210 Audi S3. I do have 1 or 2 issues im hoping you guys can help me with. I just had the downpipe changed a few days ago as a whole emerged from me getting alittle to happy with my right foot. the noise sounded like a blown exhaust but after changing the downpipe it went away. The noise is now slowly returning in the lower rev range (2k). Also the turbo is making an odd whistling noise and sometimes stops pulling for a second around 4k. does seem to be a bit down on power and the turbo feels like its sturggling. Hope you guys can help me, cheers..
