It changes the fuel mapping in the ECU, giving the car more fuel than it does
now.

You are correct, there are downsides. The biggest is that because of more fuel
injected into the combustion chamber, it will burn hotter. It may not be
damaging, but it could be. It has happened on some engines. I would very much
like to have a chip installed in my Syncro (112 hp aint enough :-)) but I'd
complete it with an exhaust gas temp gauge to see if it runs hotter, or too hot.
