return to stock, then reload your desired tune!!!!!

What if you do not remember if you are already stock?

 

[grasshopper]

The tuner will tell you that when you go to program it, if it has a perform tune in it, the tuner will ask you when you plug it in if you wanna return to stock!!!! if it just goes to the menu tune it and diagnostics, the truck is stock!!!!!

if you plug it in, go to...... option ........car tune .........it will show stock or the tune you have installed

Like runmax said, click on options, scroll down to the last option and click enter, it should tell you there.
