Ok.. for the 5 year olds:
Most cars that truly get tuned have a turbo charger which helps the engine make more power.
When they make cars the computer controls how much power the engine makes. They don’t want cars to break down so they don’t give it too much power.
When people tune cars they tell the computer to let the engine make more power even if it means it won’t last as long.
When people tune cars that don’t have a turbo they are usually putting on some fancy looking parts that don’t make it faster in any noticable way.
For the 16 year olds.. these are things like a really loud muffler, a cold air intake, lowering springs and giant wings on the back.
