Do I need a power supply to load the 91 oct. CAI tune in my 07 Charger 5.7?

Thanks

No. When you plug the Predator in to the OBD port it is powered up.

Can't load it, I need to get a update. I will get the power supply tomorrow and try again. Will the update be r19 or r20? From what i've been reading
r20 doesn't work that great in the 07 Charger R/T's.

Thanks Subime.
