    • Performance Chips
      Are Superchips Really Super?
      Although most automobile manufacturers try to achieve a balance between performance and emissions when the ECU is programmed, in reality more power can be obtained when certain engine control parameters are changed. Aftermarket superchips are made to adjust parameters to increase engine power and torque. The superchip gives a “boost” to your vehicle’s performance by enabling you to adjust the settings for the ECU, and allow more fuel to be injected than the factory settings provided.
    • Performance Chips
      Why Should I Add a Throttle Controller?
      The throttle controller will basically bypass the computer in the vehicle. It is designed to take the information right from the accelerator position sensor and compile it in a high speed controller circuit that compiles the signal sent from the Accelerator position sensors. With this controller you are able to program it to different options and the throttle response timing will be noticeably faster.
