For sure if you own the car, you can modify it. Tesla has been doing something similar for a while on the extended range model 3 where you can pay a one time fee to get a boost in performance. Interestingly, there is a Canadian company that has reversed engineered what happen when it is unlocked and is selling a device that you plug on the car CAN bus and you get the same performance boost. They obviously sell this for less that what Tesla charges and as far as I understand, the only risk is that you might void your warranty if Tesla "catches" you doing it. So I kind of agree that it seems similar to getting a factory approved chip tuned. When you chiptune your ICE car, you will often pay several hundred euros for a shop with the right hardware to modify your car (and loose your warranty). In this case, if the setting change is increasing failure rate but your warranty is not affected maybe it's not such a bad deal.
