Yes, curious if that will work.

Previously had '15 RT 5.7 and put Stage 1 Scat Pack kit omit so have stock spare PCM. Upgraded to '16 Scat Pack and curious if I Diablocan use the 5.7 PCM to tuner for the new Scat Pack.

Recently installed Scat Pack Stage 1 kit (mufflers, CAI, and Modified PCM) in my 2015 Charger RT.

Tazer from ZAutotech has a tool that can accomplish this. It's a good tool, around $300.
