I3 on my ram, can be used on Chevy?

[Rob]

I have an unlocked pcm and used my i3 to tune my 2016 ram 1500. Now my wife just bought a 2018 silverado, anyone know if I can just purchase a license for my i3 and install a tune? And if so, do the new Silverado's need anything else like an unlocked pcm?

Thanks

Yes, you can do this.
The 18 GM will require an unlock through ignition, but no need to send pcm in.
