Removing Diablo PCM

[TopCat21]

Greetings,
I installed the Diablo modified PCM with the Trinity 2 combo last year. I see many posts and Q&As on removing the tune back to stock. No problem. But if I just want to reinstall the stock PCM, at what point after selecting Performance Tune; Original Backup, can I swap the stock PCM back into the vehicle?
Or, can I just swap PCMs without resorting to original tune on the T2 menu since I’ll be keeping the modified PCM in storage.
Once the stock PCM is connected back to the vehicle, what if any additional steps need to be performed? Or simply just remove the Trinity 2?
Thank you.

you can just wap pcms without any tune changes, thats probably easiest.

if prepping for dealer, i would put stock tune back so pcm/tcm are both stock in case they decide to update anything.
