LIVERNOIS MOTORSPORTS 2021 JEEP WRANGLER 392 RUBICON 6.4L TUNER WITH PCM UNLOCK
- Product Information
- Vehicle Fitments
The Jeep Wrangler is a timeless vehicle with amazing capabilities right off of the showroom floor. With the release of the JL version starting in 2018, many improvements that customers were longing for were made, but one area that they still left room for improvement in was the engine. While we offer amazing gains on the 3.6L Pentastar with our tuner, there really is no replacement for displacement. So after years (more like decades) of customers asking for a V8 in a Wrangler, Jeep finally delivered! Well, this provided us with an amazing opportunity to make what is good even better! First to market with performance enhancing calibrations, our new MyCalibrator performance tuning device is available exclusively from Livernois Motorsports for your 2021 Jeep Wrangler Rubicon 392. With our performance tuning, we are able to gain nearly 35HP at the tires with the use of 93 octane fuel!

What Goes Into a Livernois Motorsports Custom Tune?
- Fuel Mapping- The fuel map inside the ECU is able to adjust the air/fuel mix for maximum efficiency and performance in any condition.
- Rev, Top Speed Limiters and Shifting Characteristics- By dialing in the optimal RPM range and pressures for your transmission to shift at we are extending the life of those components. We also take this opportunity to revise your top speed limiter. These modifications are made to make sure that you are able to have a long-lasting and fun life with your vehicle.
- Ignition Timing- Timing is where we control when the combustion event occurs. By revising the moment this happens we are able to increase your vehicle’s performance and efficiency!
- Torque Management- Using our proprietary tuning software we alter when, where and how the computer tries to step in maintain control over your vehicle in a performance setting.
- Tire Size Alterations
