I think this is it. I have tried, tried, tried to get it to throw a code. No dice. Went back to the dealer, and the foreman and I went for a ride. Car definitely feels faster from the passenger seat. I think it's all in my head. I was sooo used to 400+ whp that yeah, the car feels muted. On the plus side, I've never heard an N54 that didn't rattle, so it is really weird to just hear the engine now, even on decel. Time to put everything on + flex fuel.
