Key Features:
- Unrestricted Power Delivery: Properly adjusts factory torque monitoring maps to completely eliminate ECU power cutbacks.
- Speed Limiter Removal: Fully deletes the factory top vehicle speed limiter.
- Enhanced Thermal Control: Optimizes intercooler coolant pump flow parameters to actively drop intake air temperatures (IATs).
- Calibrated Cabin Displays: Recalibrates the factory dashboard HP & TQ gauges to accurately display your vehicle’s true upgraded output.
- Exhaust Flap Customization: Adjusts exhaust valve logic with the ability to fully remove or open the flaps as required.
