As all of the others have said...it will not hurt your truck, but it will hurt your mileage if you are not doing stop and go driving. It does two basic things...It increases the rpms of the upshift point making you think you have more power...it prevents the 6th overdirve gear from engaging, again giving you quicker kick responsiveness to your throttle. You will note that sport mode works only in Highway mode, and in another other Terrain Response mode, it changes to manual shift.
There are probably some minor issues in the fuel injection timing as well, but that is the mileage part.
