Hello, looks like no one has any info, and my searches came up with nothing. I can only assume the tuner is reading what the PCM shows as possible, and it doesn't list the 3.64? Or visa versa, the tuner itself wasn't programmed to offer the 3.64 choice. I'd think you may have to go to the source and ask Diablosport

Be sure to chose the correct forum (Predator 2, or Legacy Predator)


Please post back with the fix if you get one

Im not aware of any 3.64 pumpkins that will swap into a pre-2015 RWD Challenger. Have you already located the diff unit? What is the donor vehicle?

Apparently the 4 speeds could just be swapped in the 5 speeds, so idk whats going on probably just an odd update on diablos side because i have the five speed and i know it can fit, If not ill just redo the rear end and slap some SRT gears in it 🤷

There’s a greater than zero chance you could just set the gear ratio to either 3.55 or 3.73 and it would be fine. You’d have a speedometer that wasn’t correct, but having it go into limp mode would be the main concern, and at such a minor difference from actual to configured, I’m thinking it would not limp on you.

But yes, if you can get an updated gear ratio listing with the 3.64 available from DiabloSport via an update or something, that would obviously be much more preferable to my experiment. 🧐
