From the factory the vast majority of cars are detuned and this is for one simple reason. Any motor you buy will be designed to last for hundreds of thousands of miles in the most extreme conditions possible. Manufacturers have to take into consideration that their cars have to not only work but remain reliable all around the world, from -40 °C snowstorms in Finland to 45 °C desert conditions in the Middle East. They also have to account for the availability of decent quality fuel.
And that’s the biggest point: we have good quality fuel here, and the temperatures aren’t in any way extreme enough to affect your car. That means you can use software to make the most of these conditions and any supporting mods you’ve fitted, all the while keeping the engine within safe parameters.
Everything from simple off-the-shelf port maps to full-on custom and live maps on a rolling road are designed to electronically tweak engine settings like boost, fuel delivery and engine timing, to increase power, or mpg, or drivability, or all of the above.
