Magnuson 01-19-36-003-BL Supercharger for 18-21 Jeep Wrangler JL and Gladiator JT with 3.6L Engine
Magnuson’s fully redesigned Jeep 3.6L V6 Supercharger System is engineered exclusively for the Wrangler JL and Gladiator. A truly remarkable product, this TVS1900 supercharger operates in its peak thermal efficiency zone for almost the entire engine duty cycle, resulting in super-low inlet air temps for massive gains in horsepower and torque, producing V8 levels of performance from your factory V6. Providing an AMAZING 440hp AND 380 ft-lbs OF TORQUE at the crank, equivalent to ~372 REAR WHEEL HP. That’s 59% more power than the stock V6. while also creating 22% MORE HORSEPOWER THAN A 5.7L HEMI V8. The install can be done in a day with minimal vehicle downtime (note that a couple of extra days are required to send ECU out for unlock/re-flash) and is easy to convert back to stock - no cutting or welding required, and no need to swap transmission/cooling/exhaust/AC/wiring systems.
Note: Not for eTorque V6 engine with 48v Stop-Start mild hybrid system.
Note: Not Carb approved for 21 & newer models
Not compatible with GPEC5 computers. Gladiators and Wranglers with build dates starting in August of 2021 started using this PCM.

Magnuson Supercharger Reviews
I am not someone who leaves review too often but I felt compelled to leave a five star review for Magnuson. I purchased this supercharger for my 2021 Jeep Wrangler Rubicon 6-speed manual a little over a year ago. I installed the supercharger myself in my driveway. The Magnuson installation instructions were extremely well written. The installation took me 10 hours over two days with simple hand tools. I did run into an issue with the O2 sensors showing a code. Magnuson went up & beyond helping me with a custom tune for my Jeep. Since I installed the custom tune I have zero warning lights. I have over 5,000 miles with the supercharger without any issues. My Jeep idles very smooth. Fuel milage is not too bad either. The power and torque increase was exactly what my Jeep needed to turn 37" tires. In first gear my Jeep launches hard. Yet I normally drive my Jeep like it's a Jeep, not a sports car. I truly believe this is an amazing product. To run a supercharger in any vehicle requires an understanding that you need high octane fuel and use top shelf oil like Amsoil with frequent oil changes. To have a supercharger on a Jeep it's not a sports car so driving it like one could be destructive. My final thoughts are this supercharger kit from Magnuson is amazing and well built. I am not sure what happened with the Jeep in the previous review but it sounds like the installation was not done per Magnuson instructions. Hopefully the other reviewer was able to get his Jeep straightened out. I will say I don't believe the fault in that Jeep's failure was due to the supercharger Magnuson designed for the Jeep Wrangler.
Instructions appear to be very good.
Worst product ever
Spent 10,000.00 drove it for 2 months started having problems going back to dealer who installed it. After 6 months it blew my engine.
Of course magnesium won’t honor warranty
Stay away I say zero stars
Questions
The primary challenge in installing this supercharger on a vehicle with a GPEC5 PCM (found in some 2021 and all 2022+ models) is the PCM's security and the ability to tune it. The supercharger requires a specific engine calibration (tune) to function correctly and safely with the increased airflow and boost.
As of my last update in April 2025, here's what you would need to do to install this Magnuson supercharger on a vehicle with a GPEC5 PCM:
PCM Unlock and Tuning Solution: The most crucial step is to have the GPEC5 PCM unlocked and a custom tune developed for your specific vehicle with the Magnuson supercharger.
HP Tuners: As of early 2025, HP Tuners has announced support for unlocking and tuning select GPEC5 PCMs, including those in the 2022-2024 Jeep Wrangler 3.6L and 2021-2024 Jeep Gladiator 3.6L. This service typically involves sending your PCM to HP Tuners for a one-time upgrade. You will also need an HP Tuners MPVI3 interface and credits to license and tune the PCM.
Other Tuning Solutions: Keep an eye on other aftermarket tuning companies, as they may also be developing solutions for the GPEC5 PCM.
Magnuson Calibration: Some sources indicate that Magnuson works with HP Tuners to provide calibration files with their kits for supported vehicles. It's essential to confirm with Magnuson if they offer a tuning solution or a base calibration for GPEC5-equipped vehicles.
Verify GPEC5 Compatibility: Even if a tuning solution exists, double-check the specific build date of your 2021 vehicle. Some 2021 models still used the older, more easily tunable PCMs. The GPEC5 was generally introduced in vehicles built from August 2021 onwards. You can usually find the build date on a sticker inside the driver's side doorjamb.
Professional Installation and Tuning: Given the complexities of supercharger installation and the critical need for proper tuning on a GPEC5-equipped vehicle, it is highly recommended to have the installation and tuning performed by a reputable shop experienced with Jeep modifications and forced induction. They will have the necessary tools, knowledge, and software to handle the PCM unlock and custom tuning process.
Hardware Installation: The physical installation of the Magnuson supercharger kit itself should be similar to the non-GPEC5 models, as the engine hardware remains the same for the 3.6L V6 during those years. The kit typically includes all the necessary hardware, such as the supercharger unit, intake manifold, intercooler, fuel injectors, and mounting brackets.
In summary, to install the Magnuson 01-19-36-003-BL supercharger on a GPEC5-equipped Jeep, you will primarily need a viable solution for unlocking and tuning the PCM. As of April 2025, HP Tuners offers this service for certain GPEC5-equipped Jeep models. It is crucial to verify compatibility with your specific vehicle's build date and to have the installation and tuning done by experienced professionals.
The product description mentions that this kit uses a TVS1900 supercharger. TVS stands for "Twin Vortices Series," which is a type of Roots-type supercharger.
Roots-type superchargers do not use helical gears for their primary compression mechanism. Instead, they typically use meshing rotors with multiple lobes that trap and move air. The rotors can have a helical shape to improve efficiency and reduce noise, but they are not gears in the traditional sense of transmitting rotational motion between shafts with meshing teeth.
Therefore, while the supercharger unit itself might contain various gears for its internal operation (like timing gears for the rotors), the Magnuson 01-19-36-003-BL supercharger kit does not primarily rely on external helical gears for its main function of compressing air.
