As someone involved in modified cars, these are very different things. There's only 1 real way to change your brakes. It's like LEGO, except with a couple of bolts and some metal pads. Adding a turbo increases power (or fuel economy) but isn't going to cause your car to accelerate on it's own. Or lockup steering. Or push timing and blow holes in your engine sidewall. All that stuff is computer controlled in modern cars, and you bet your ass you can cause some extremely catastrophic failures just with poorly implemented software.
