Wastegate Rattle?



The sound goes away when I change the procede comp settings from 90% to 45% - To me it sounds like a dang exhaust leak, all flanges are tight and show no signs of leaking and the downpipe clamps are tight.

I had a problem about 2 years ago with this same deal and they replaced the turbochargers, but I can't recall what it sounded like, most exhaust leaks get louder as you rev but this only does when letting off which is what i remember my wastegates doing before. Sorry for the poor mic on the camera.

All our lifts are being used at the shop right now, so I figured i would go to the community really quick

I did notice they extended the warranty to 8yr/80k - Mine should already be covered under the 2 year unlimited mile replacement warranty.
