>Those parts are made by company's that work with car brands to make compliant parts. You have some written guarantee that Joe didn't zip tie some frozen hot dogs to his brake calipers so he could make dinner and stop his car? I don't. I don't get why only Tesla should write engine software for their car, and completely lockout "Joe's all pro turbo" from doing the same. I can get a custom rom for my car now, so why can't I for the Tesla? I get it voids warranties, but not at all is a problem.
