Remapping a McCormick
Every McCormick leaves the factory on a calibration written to suit every market it sells into, on fuel of varying quality, with service intervals that get ignored. That margin is what a remap works into. We read the original file off the car, write to it, and keep a copy of the standard file so it can go back exactly as it was.
What your car gains depends on the engine rather than the badge, which is why the figures sit on the engine pages rather than here. Find your model above, then your year and engine, and the numbers are on that page along with the price.
