If you aren’t planning on doing mods to the car I would go with the Pedal Commander. If you’re going to do mods you may want a tuner.
I bought HP Tuner cause there was a supercharger tune on my Challenger of unknown origin and only the HP at that point was capable of reading it (amazing technology to my rescue). I desperately wanted to disable MDS and plan to change diff ratio. I read that Diablosport can now be used on multiple vehicles as can HP. And your's may be locked which requires further investigation / consideration, where mine was not.
A tune will cost you around $1000, but you will have about a extra 40hp/tq at the wheels plus your throttle will be much better. I did this to my 2020 Challenger GT 3.6. The guys in TX emailed me a tune file. The $1000 is for HP tuners and credits plus the unlocked service and the tuners files. 93 octane..
