This looks to have already been discovered years ago as this company sells an OBD2 plug that can toggle all of this stuff, as well as highjacking some controls to add new functionality, as well as adding 50HP to those cars with a specific rear motor version https://ingenext.ca/products/ghost-upgrade
Is this method software only? Because the upgrades on that site are pretty expensive and proprietary.
If you read the article it is different. This relies on physically bringing connections to gain root access to the file system.
It's also unlikely Tesla can't just watch for modified files and update them everytime the car goes into drive or something. They probably won't do it, but to claim it's impossible is just disingenuous
