That is called chip-tuning and being done since years.
The only think is, no OEM does this officially. It is only done by more or less shady third parties. Officially it is done eg. by Brabus for Mercedes, Alpine for BMW, …. But then not part of a retrofit but you have to buy the whole car from them. You can buy it as retrofit from some Russian or other alike.
It is also very common in the industry that the very same engine is used with different algorithms resulting in different PS. Like my Volvo S60 2001 Model uses an engine which was available with 140PS, 170PS and 210PS. The very same engine was used by Ford at that time in different Models with different PS.
