Every mod you do changes the way in which air is moving in or out of the engine. When you change the way air is moving in or out of the engine the fueling also has to change. That's why you should tune after each set of mods that you do. A stock engine would almost always benefit from a tune as well because usually performance cars come from the factory with a conservative tune.
Hope this helps,
