If you can show the dealer that the WGs don't shut anywhere close to that spec, AND the WG shaft on the rear turbo is fairly loose/sloppy, that should definitely qualify for turbo replacement under the 82k mile extended warranty. I say rear turbo because you can easily grab it with your hand and feel the play, while the front is buried against the engine. Make sure the engine is COLD, though, or you will end up with severe burns! Those turbos stay hot for a very long time after shutdown.
