This represents a gain of approximately 99 HP and 60 lb-ft of torque. The system utilizes RENNtech's proprietary tuning module, which stores both the tuned file and your vehicle's original stock file.

This offers a versatile solution for performance tuning.\n\nThe Hand Held Tuner (HHT) is included with this upgrade, providing the user with the unlimited ability to switch between the RENNtech tuned file and the vehicle's stock ECU programming. This feature offers flexibility and convenience for the driver.
