Lost tune

I just spent a couple days tuning a Viper. Once completed I thought I’d test it against my best bought tune. All in all it turned in the same time, so I’m happy with that. So now I go back to load my tune and it’s gone?
So, is there a way to switch between your own tune, and a bought tune, and back again?

Yes. You just have to save your tune. The only way your tune is “gone” was because you didn’t save it or you accidentally deleted it. Save, save and save. It happens to us all.

OK. How do you Save it?

the same way you load a setup really.

but instead of picking load setup choose save setup.

Thanks
