Hey guys,
Quick question, I need to take my car into the dealer tomorrow after work to have my bumper fixed and recalls done. I forget the process to revert my Diablo tune for a 2015. I have the spare PCM. Do I need to take the tune back to stock and then swap to the OEM PCM, or can I just swap to the stock PCM? I also have the trans tune.

No. Doing their TSB's won't lock the PCM again but if it makes you feel better then change the pcm :)
I took the tune back to the original in the tool. It only did one write, not two like it usually does for the trans tune as well. Took it for a spin and it doesn't feel like it's back to stock. Did a 0-60 for comparison... It burned rubber quite a bit laying into it. It did stall heavily instead of shifting right before 60 mph, and it still hit a 7.13 0-60 on the Trinity... Doesn't seem as juiced, but still a bit too juiced to me... Maybe it's all the mods still making a difference without a custom tune...

Anything special I need to consider for reverting back to stock since I have a hemifever tune? The custom tune isn't even an option in the tool anymore... Been so long since I've had to putz with this that I forgot the whole process.

You will see « custom tune » after you have loaded the hemifever tune into the tool.
