Expect a substantial increase in performance with this simple plug and play modification.Your vehicle is equipped with a Bosch Motronic engine management system sometimes referred to as an Engine Control Unit (ECU), or Digital Motor Electronics (DME). It's essentially a computer that's responsible for controlling various engine control and performance parameters. Parameters related to airflow, fueling, and ignition timing among other things are optimized by our engineering team to increase horsepower and torque. To improve upon the factory calibration, we replace the original chip with our performance chip that has new mapping designed to get the most out of your vehicle. Simply plug and play, run a minimum of 91 (R+M)/2 octane fuel, and enjoy a healthy increase in horsepower and torque. We optimize idle, part throttle, and wide open throttle operation, increased redline on manual transmission vehicles, and optimized fuel economy during light load operation. All of our chip upgrades are emissions friendly, and most applications are CARB compliant.These upgrades were made in partnership with our sister brand Dinan Engineering.
