Which vehicles can be fitted out with Powerbox tuning boxes?
All diesel vehicles with pump nozzle injection, Common-Rail injection, VP37 diesel pump as well as VP44/VP30 /Lucas diesel pump.

How do Powerbox tuning boxes work?
These electronics are used in vehicles, which are equipped with conventional electronic fuel injections from the manufacturers Bosch or Lucas. By a change to the fuel injection pump signals from the control instrument to the fuel injection an increase of power is produced. Performance can be improved by up to 40 hp in some cases.

What are the advantages of Powerbox tuning boxes?

• design, which is kind to the engine
• made in Germany
• quick assembly/dismantling
• no intervention in the control unit
• suitable for everyday use
• guarantee for our product

What affect do Powerbox tuning boxes have on fuel consumption?
As long as the vehicle is driven in constant or defensive manner fuel consumption remains the same or decreases. A "before and afterwards-check" on a Mercedes 220 CDI on a test drive: 30 km country road, 10 km inner city and 30 km motorway yielded a fuel reduction of 1.2 l / 100 km with defensive manner of driving and at a maximum speed from 140 km/h on the motorway.

Why less consumption?
Because of the Powerbox tuning boxes the torque characteristics of the engine change and become fundamentally more elastic. Therefore you can drive in town with less gear changes. Every gear change means continuously accelerating and braking the mass and uses most fuel. So the number of gear changes, which would normally be needed, is reduced as well as the fuel consumption = > higher torque = lower rpm = lower consumption.

Does my vehicle smoke after installation of the Powerbox tuning boxes?
No. Only badly adjusted vehicles produce soot.

What affect do Powerbox tuning boxes have on top speed?
Powerbox tuning boxes were developed to increase and optimise torque at lower and middle rpm. Top speed is nevertheless increased in some vehicles. This lies in the region of 5 -15 km / h and depends on the vehicle.

Why doesn't the manufacturer set the vehicle up optimally from the start?
The manufacturer builds a car for the worldwide market. In other countries the fuel often doesn't correspond to our quality standards. Continuous operation in extreme heights can also worsen combustion. These are qualities, which don't have to be taken into account within Europe though. Furthermore the production tolerance can also play a role. The performance may have to be raised a little when the vehicle is on the testing stand after production. Because of this tolerances are necessary.

Do Powerbox tuning boxes have an effect on the vehicle emission test (AU)?
No since the valid vehicle emission amounts are not changed. Therefore there are no problems when having the vehicle tested (AU).

Do Powerbox tuning boxes need to be registered in the vehicle documentation? (only Germany)
Yes. Powerbox tuning boxes need to be individually registered in the vehicle documentation (this can be carried out in our workshop) .

Do Powerbox tuning boxes work in automatic vehicles too?
Yes, these have another control unit, but it has no influence on the increase in performance. This automatic system adapts automatically.

How long does the installation take?
The installation takes 15 minutes to 1 hour depending on the box type.

Can I carry out the installation?
Yes. Powerbox tuning boxes were developed so that you can carry out the installation yourself without any problems with help from the enclosed instructions.
