I bet jimberg is right about computer controlled cars. Some outfits have the ability to burn custom computer chips though and so can change anything they want to. Of course they have to know what they're doing to help you any. Timing and fuel curve maps can be made better for performance and probably sacrificing some drivability and economy.
