They now have the secondary unlocked PCM kits (intune or Trinity) available for the 22 Rams. Placed my order yesterday. I'll probably go with Sean at HemiFever tuning again as the custom tune and trans tune was night and day difference on my 15.

Anyone else running Diablo and custom tuning on their 5th Gen?

I have both HF and Jay Greene tunes on my 19 Rebel. Both make huge differences, especially shifting.

Much difference between the two? Not likely, I assume.

They have different approaches of getting to a common end if that makes sense. The around town driving experience is more aggressive with HF's tune, where I feel Jay's pulls a little harder at WOT. Off the line they're pretty similar.

The secondary PCM is just to have an unlocked PCM for tuning that can be removed to have the factory original PCM put back in at any time. You can also get your factory PCM unlocked and tune that.
