Its just a case of computer adaption, only extremely small differences in machine built engines and just slightly more tolerance in a hand built unit.
From personal experience with the AMG's the engines are all born within 1-2 horses of each other, how they develop from there depends on who owns them and how they drive.
About the adaption it happens very fast as the MAF senses the increased airflow the ECU add's fuel.
Altitude plays a huge role with these being N/A engines the ECU can only compensate by reducing fueling per firing and you end up with a loss of power.
Best time to drive is when its right around 0 degrees at sea level, they love it.
