Our Performance Chips work by sending a constant signal through your factory data port (OBD2 port) to your engine control module (ECM). This signal triggers the factory ECM to several areas of your vehicles programming including the fuel and air management as well as ignition curve and timing giving your vehicle a cleaner/stronger/and safer running motor. This piggy-back system is one of the safest and easiest performance enhancers available, leaving no trace of footprint behind. This means you will receive very noticeable gains in performance and fuel economy while maintaining your vehicles manufacturer warranty. The performance chip is a dyno tuned fuel map tuned for your specific model vehicle changing air/fuel mixtures, timing, and spark. If the vehicle is turbo or supercharged, your performance chip will also increase boost pressure.
