Livernois Motorsports now offers a PCM unlocking service and tuner bundle, enabling Jeep Grand Cherokee owners to unlock the performance potential of their 3.6L engine (model years 2015-2022). Previously exclusive to Livernois customers, this service is now available to anyone wanting to utilize commercially available tuning software.
Since 2015, tuning a Mopar vehicle like the Jeep Grand Cherokee requires physical modification to the PCM (Powertrain Control Module) to access and enhance horsepower, torque, and overall performance. Livernois Motorsports simplifies this process with their comprehensive unlock service and tuner package. Choose return shipping at checkout for a turnaround time as quick as two days (including shipping). After purchase, simply ship your Jeep’s PCM to Livernois using your order number as a reference. The unlocking process typically takes one business day.
This tuner bundle includes one performance tune and one tow tune designed for a stock, unmodified Jeep Grand Cherokee. Additional tunes tailored to specific modifications are available as optional add-ons.
With the Livernois Motorsports tuning solution, Jeep Grand Cherokee owners can expect:
