Ok, so I'm admittedly new to the car repair/modification world so this may sound like a dumb question.
I was read the below article on the legality of hacking your car and it got me wondering, is it illegal to use a tuner on your car? Obviously thousands of people do it every year and I plan on getting a tuner for my car in the near future. But I had no idea that it could possibly be illegal to use it on the car.

Is it illegal to use a tuner and does it void the manufacturer warranty on the car?
