427, I do believe you need to read:
"For maximum performance lap after lap, a concept cold-air intake system has been fitted to the 2.0L turbo engine and a calibration upgrade to its controller optimizes performance across the rpm band."
The tune WAS changed for the cold air kit (as evidenced by, "and a calibration upgrade to its controller optimizes performance across the rpm band" as stated in the article).
Again, you want to argue, but there are plenty of us that already know more than you do. And just because we do, you won't accept what is already known.
