Let's suppose that I took my car in for some warranty work such as rattling AC vents, and cracked leather seats. And to prevent a crooked technician joyriding in my car, I use a Predator (or equivalent) and set the rev limiter at 2k and the speed limiter at 20. If a tech actually decides to joyride in my car, and sees that the limiters have been adjusted, could Ford void my warranty?
