As long as you don't add anything or change anything, once you have the tune right you don't have to play with it. IMO I think the FAST XFI engine management system is the way to go. Costs a little more up front but you can do so much with it. Don't have to buy new chips when you change something..... If you have a FAST system and you add something all's you have to do is re-tune it. And you can customize the tune. Might change the tune a little bit going from the street to the track.
