The PowerBox CRplus is fully digital and includes a signal variation switch with multiple settings, so there's never a problem finding the setting that's best for your vehicle. You can even turn the PowerBox off while it is still connected.
The PowerBox CRplus has been programmed for optimal performance. Power gains vary depending on engine and ECU type. CRplus users can expect a power improvement ranging from 25% to 55% greater than the gains achieved with our standard PowerBox CR. Essentially, the power improvement is linear to acceleration; however, a greater boost is provided when there's an immediate demand for acceleration. This reduces the time required to pass other vehicles, and, in some cases, means less time exposure to oncoming traffic.
Despite its potential for tremendous power improvement, the PowerBox CRplus has been programmed to provide better fuel efficiency. Its unique programming increases power when needed most. During acceleration, the injection time required to achieve higher speeds is substantially reduced. This minimizes fuel consumption. In fact, independent testing revealed fuel economy savings from 10% to 15% at signal variation settings between from "3" to "6".
