Newbie question about tune

[Speedo1]

So not sure if I screwed up. I followed the directions in my 2016, Silverado 5.3. I installed the 87 canned tune, and I did back up my stock, tune. After I installed the canned tune, I remembered that I also wanted to turn off the AFM, increase the TPS, and firm shift the tranny. So I went back in to Advance parameters and I went in and turned off the AFM, and I did the other things that I wanted to do. Then, when I backed out, it said install tune, and I said yes. So it looked like it reinstalled the 87 canned tune on top of the 87 canned tune I just installed. Did I screw up and lose my stock tune that I saved? Thanks

nope, stock tune is always stored until you return to stock

Awesome! Thank you very much.
