Common Rail Power Tunning

The Powertunning CR works by modifying the electronic signals that control fuel pressure produced by the pump in order to optimize engine performance. The PowerBox CR increases fuel pressure at the pump to maintain rail pressure in the mid to upper operating ranges. In effect, pressure accumulates faster in the rail and is readily maintained to deliver more power and torque. The Powertunning CR engages when rail pressure is at or above 1,600 bar or 23,000 psi.

The Powertunning CR includes plugs that are compatible with those originally installed in your vehicle. The Powertunning CR is easily installed directly to the common rail pressure sensor. With the instructions provided, an inexperienced driver can complete the installation in 5 minutes. The Powertunning CR 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.
