Well, the engine is not louder with 29.2+, the EXHAUST is (turbos muffle the exhaust, so the more gasses going through the turbo, the quieter it is...hence 29.2 being way louder than pre 29.2). Either they are idiots and someone who knows nothing about cars wrote the bulletin, or, they mean wastegate rattle might return. That is what I'm guessing. Basically, they are probably warning people the wg's might rattle, and not to complain. Fat chance. I want my $50,000 cake and I want to eat it too. No laggy - no rattly.
