PCM Unlocking Service and Tuner Bundle

The Underground LPP621142 is a PCM unlocking service and tuner bundle specifically for the 2015-2023 Dodge Challenger equipped with the 6.2L engine. This offering provides a solution for Mopar vehicles, where tuning traditionally requires physical modifications to the computer (PCM) to enhance power and performance. This kit includes custom tuning via Livernois Motorsports, promising increased horsepower and torque (+64hp/26tq with 93 Octane fuel), enhanced throttle response, and dyno-proven air/fuel adjustments. It also features modified fan settings for reduced heat soak, transmission shifting improvements (reduced torque management and increased shift firmness for automatics, and removal of the "Skip-Shift" function for manuals), raised top speed limiter, and the ability to read/clear diagnostic trouble codes (DTCs). Post-purchase, customers will ship their vehicle's computer to Livernois for unlocking, with an estimated turnaround time of as little as 2 days including shipping. A Windows PC is required for tuner updates, as MAC/Apple OS is not supported. Additionally, 2018+ vehicles require the "Bypass Cable, Part #LPP621000". This unlock service is intended for the vehicle's original ECM; if a new or used ECM from another vehicle is being provided, contact Livernois prior to purchase as additional costs may apply. This product is noted as "Item not for sale in California" and is also described as being "for Racing Competition only and is not legal for use" on public roads.
