  A performance chip is an electronic device that enhances automotive engine power, fuel economy, horsepower and acceleration. The best kind of performance chip provides tuning throughout the vehicle's RPM range, collects data about your driving and transfers that data into enhanced performance for your vehicle. In the world of performance chips, there are five brands that stand heads above the rest: Superchips, JET, DiabloSport, Edge and Bully Dog.
