If you are thinking about supercharging your Grand Cherokee, there are a couple things to consider:
91 Octane (minimum) fuel is a must. So, there is the added cost for premium gasoline.
Fuel economy. I went from 20 MPG down to 18 MPGs.
AND then there is the $10,000-ish price tag.
ProCharger offer two systems. Tuner kit (No tune, fuel system parts, or PCM), and the Complete System which comes with everything needed to install and run…
Parts installed:
Included with the ‘Complete’ System:
ProCharger P-1X-H (P-1X-H upgraded item)
ProCharger Air-to-Air Inner Cooler
39.5 lbs Fuel Injectors
Windshield Washer reservoir (replaces the OEM)
Coolant Overflow reservoir (replaces the OEM)
HP Tuners Unlocked ECM (part of the Complete system)
ProCharger 2 Bar Tune (part of the Complete system)
*NGK Spark Plugs (LTR6IX (1 Step Colder)) (Highly recommended)
*MSD Coils
*Mishimoto Radiator
*Mishimoto 180-degree Thermostat
*Mishimoto Silicone Radiator hoses
*HP Tuners MPVI2 interface (additional tuning options)
*AutoMeter Ultra-Lite Gauges
Air/Fuel Ratio (AEM-4370)
Fuel Pressure (ATM 4371)

**Upgraded my gauge set
AEM Gauges
Air/Fuel Ratio (30-4110)
Fuel Pressure (30-4401)
Boost/Vacuum (30-4406)
Gauge Pod (ATM 5288 (it isn't my favorite, but it works. I am hoping to find an A-Pillar Triple Gauge Pod)).
** Parts that I had already installed:
Corsa Sport Cat-Back
AirLinks (to lower the ride a little bit, and AlfaOBD to fine turn the ride height that I was looking for).
1.5-inch Titan Wheel Spacers
What does it take to install a ProCharger System?
When the ProCharger System arrives, the first thing that you are going to want to do is an inventory. Make sure that you have everything that is supposed to come in the kit. I didn’t have any issues here.
The kit is going to come with an RTD Interface and RTD Flasher software to download the information from the stock (OEM) Power Control Module (PCM). I have a dedicated laptop computer for tuning my Jeep.
Install the included interface drivers and the RTD Flasher software.
Open the RTD Flasher program.
Click on the “Help” tab.
Click on the “About” option. This is going to look for and update the RTD Flasher software. Close the window when the update is complete, or No update found is displayed.
Click on the “Help” tab.
Click on the “MPVI2 Verification Code” tab. Write down the Serial Number and Verification Code. You will need this information when registering you RTD Interface. You can select the “MPVI2 Verification Code” tab while registering your device to ‘Copy and Paste’ the numbers.
Go to the HPTuners website to register your device (RTD Interface). Follow the prompts.
Click on the “Resync Interface” tab to update the interface. At Resync Complete, close the window.
WHAT you are going to have to do (the instructions could use a little help here).
I put the vehicle on a charger to keep the battery from getting weak during the read and Flash procedures.
Open the RTD Flasher program.
Connect the RTD Flasher to the vehicle and turn it to the Run position, DO NOT START.
Click on the icon that reads “Read Vehicle”.
Click on the “Read” button.
In the top Hardware: drop down, CHOOSE “GPEC2, 2018+ Dodge” (this isn’t in the instructions).
In the lower Hardware: drop down, CHOOSE “ZF8HP, Dodge” (this isn’t in the instructions).
Choose the “Read” button and follow the prompts (mine took 14 minutes to read the ECM and 6 minutes to read the TCM (glad I was on a charger)).
Save the calibration file so that it can be emailed to HPTuners (I bought my ProCharger through Joe at FastHemis.com, so I sent my files to Joe, and he sent it to HPTuners). HPTuners will build a new unlocked PCM for the ProCharger “Complete” system. (this isn’t in the instructions).
I called mine: Stock Calibration - 2020 Jeep Chand Cherokee Trailhawk 5.7L, V8.rtd
And send it to HPTuners. A couple days later I received my new Unlocked PCM.
** tech tip; When you get ready to install the ProCharger “Complete” System. Disconnect the battery, install the new unlocked PCM, reconnect the battery and read the calibration from this new unlocked PCM. Follow the instruction previously listed above EXCEPT read ONLY the ECM Hardware, DO NOT read the TCM’s information, leave it blank. You will send this information (calibration file) to ProCharger for a Modified, ProCharger, 2 Bar Calibration file that is going to be required to run the ProCharger on your engine. HPTuners needs the ECM and TCM to send you a new unlocked PCM. It is going t be loaded with the OEM Stock Calibration files. ProCharger does not make any modifications to the TCM, so that file is not needed. IF you happen to send ProCharger a complete read, ECM and TCM you will have to buy (four (4) additional Credits to flash your new unlocked PCM because of the TCM information. (this isn’t in the instructions).
Now, disconnect the battery and start the ProCharger installation… ProCharger provides some surprisingly good instructions for this process.
