If you have to ask this question as many times as you have... you probably shouldn't touch your car till it's out of warranty.
A professional tune will not harm your car. If you play with the tune parameters you could cause problems. If you return your car to stock and not complete the drive cycle, the dealer can tell the PCM has been reset. All you have to say is you left the lights on and the battery went dead. Or that the battery was low so you disconnected and charged it.
