The Powertunning VP works by modifying the electronic signals that control fuel pressure produced by the VP 37 pump in order to optimize engine performance. The PowerBox VP increases fuel pressure at the pump to compensate for lost pressure as fuel is distributed to each injector. The increased pressure enables injectors to respond faster during acceleration. While actual injection pressure is not increased, the pressure required to activate injectors is readily maintained.
The PowerBox VP includes plugs that are compatible with those originally installed in your vehicle. The PowerBox VP is easily installed between the Electronic Control Unit (ECU) and the injection pump. With the instructions provided, an inexperienced driver can complete the installation in 5 minutes. The PowerBox VP will not override the safe operating parameters of your engine and does not change or interfere with ECU functioning. Other features are highlighted in the product overview below.
