If you want to update your engine computer and increase your engine's horsepower, check out our selection of ECM computer proms. These performance computer proms improve your engine’s efficiency by replacing your current engine computer prom with a newer chip meant to enhance the engine’s timing and fuel flow. Typically used in newer performance vehicles, these performance chips may also help tune the vehicle if mechanical parts of the engine have been upgraded beyond factory specifications. We offer a wide selection of ECM computer proms at O’Reilly Auto Parts for your car, truck, or SUV.
