Are you talking about tunes like the bama tunes? or just tunes in general? either way the old tunes that are on your tuner right now will be deleted and replaced by the new ones. When i recieve tunes from bama i save them in a seperate folder on my desktop and then load them so that way i have the files for later. the only tunes i dont have are the ones that were ordered when i bought the tuner orginally from american muscle. hope this helps.what happens to the old stored tunes when we put in new tunes?
your welcome, i think i said it in my other post but after the intial buy of the tuner you can save tune files on your desktop and keep them for later just in case you switch something out etc etc. I will add that your stock setting for the car is always saved and you shouldnt have to worry about that.Thanks for the answer--Yes, I meandt Bama tunes--
