If I need to disconnect my battery for a wile or if it dies one night will I loose my tune, will it go back to stock?

I needed to take the radio fuses out.
Now I loaded my tune it said flashing it got up to 100% then it Said turn off ignition. My truck really doesn't feel any different, can't even spin my tires on...
