A chip merely changes the coding that the ECU uses. For example, it may tell the engine to modify several aspects of how it operates, which, in turn, may provide some benefit to the car's performance .
For example, it may advance or retard the point at which the spark plugs ignite the fuel mixture in a cylinder.
I hope my simple explanation provides a glimpse into what a chip does.
