Introducing a ground-breaking product from Edge, Superchips & DiabloSport (All sister companies owned by Holley) – The Pulsar! The Pulsar is an in-line computer that connects directly to the vehicle PCM, eliminating unnecessary wires in the engine compartment. Since it connects directly to your vehicle's PCM, the Pulsar can control signals to optimize performance gains, throttle response, mileage, and more. The Pulsar can completely change your driving experience to optimize performance and drivability in every situation. Whether you’re towing or daily driving, the Pulsar provides an instant improvement in performance and throttle response. The Pulsar also includes adjustment features that allow you to account for any changes you’ve made to your ride. Calibrate your speedometer for tire and gear changes, read and clear diagnostic trouble codes, adjust your TPMS settings on your new wheel/tire setup, or even adjust your speed limiter. After installing the Pulsar, the only thing you’ll wonder is why you didn’t equip your vehicle with the Pulsar sooner!
