Why is my vehicle not already optimised for peak performance?
Manufacturers sell vehicles with a standard set of map files on the ECU so they can be shipped all around the world, meaning they have to deal with different climates and a multitude of fuel types and quality, this is why manufacturers set a standard map that will simply work wherever the car ends up in the world.
