2012-20 Jeep Grand Cherokee SRT (6.4)

VERY IMPORTANT NOTE: All Chrysler/Dodge/Jeep vehicles 2015 and newer have locked Powertrain Control Module (PCM) computers and they require an unlocking process in order to install a new tune. The PCM must be shipped to Diablosport for unlocking so, please allow roughly one week. Another option is to purchase a second PCM and have that one sent to 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. Read Less
