Lost the stock tune?

[stang06]

I had posted a week or so ago, about loading a 91 oct tune on an 06 Mustang GT w/ mods. Car ran poorly. I was corrected, rightly so, that I needed the custom C&L Racer tune (already loaded on my Predator). Car runs great with the last tune. My concern is, how do I know I still have the factory tune in my preditor? Can I verify this somehow? What if I do not have it...is that a big deal?

Appreciate a reply!

The predator will not allow to program a vehicle without having a backup in it so your backup is in the predator 100% intact.
