NOTE: All Chrysler/Dodge vehicles 2015 and newer have locked Powertrain Control Module (PCM) computers and they require an unlocking process in order to install a new tune. Please click on link here for more details. The PCM must be shipped to Diablosport for unlocking so, please allow roughly one week. Another option is to purchase a second PCM directly from Diablosport ahead of the installation so, there is no downtime. It is an unfortunate hassle, but unlocking is required with any tuning modification to Chrysler/Dodge vehicles.
