As foolish as this question may or may not sound, I was in the market for a chip when it occurred to me... Does a professional flash tune nullify any benefit gained from the chip, and if so what are the advantages of one over the other?

Lastly, after a flash tune on a mostly stock car, will I need a reflash after adding additional mods later on?

Yeah you will need to reflash after you add more mods.
