We are all familiar with automotive tuning shops. They try to take cars that had a certain level of performance from the factory and give them better performance. The process involves adding the right parts and adjusting things like the air / fuel mixture.
This video explains all about tuning. It gives a brief history of how we got from the early carbureted cars to the modern computer driven fuel injected cars and how tuning works on each of these cars. It also talks about those claims of chips that say they will make an additional 50 horsepower with the chip alone.
