The diesel tuning industry has been influenced by the success of the Powerbox since 1994 and its reputation is increasing. Many people all over the world, from everyday motorists without tuning experience through to major car manufacturers, are discovering this product and what it can achieve.

Whatever the reason for being out and about in your car the PSI Powerbox will always ensure an enjoyable drive! The introduction of a PSI Powerbox will make drive time smoother by increasing engine reaction and producing more responsive acceleration. The Powerbox will also eliminate ‘flat spots’ - meaning you can pull smoothly through the range of revs without losing any power. And all this without the side effects of higher fuel consumption, reduced engine life or heavy smoking!

How the increases are gained:

The power increase is achieved by dynamically re-mapping (in real-time) the can-bus digital data between the fuel pump and ECU to provide extra fuelling to the engine at the most necessary points, in strict accordance to engine speed and load. The PSI Powerbox micro-management system works in parallel with the original management system to ensure the smoothest delivery of power and torque.Because the Powerbox can increase torque, pulling power and acceleration, you will save on fuel with the number of miles per gallon achieved. Added torque also means you can hold higher gears at lower speeds as well as enabling you to change up through the gears faster - meaning you burn less diesel.

Apart from these features, it’s worth bearing in mind how compact your Powerbox will be. Not only that, it can even be fitted using the original manufacturer’s plugs, usually in twenty minutes or less. In any case, full colour instructions are included with every PSI Powerbox and our support team can help with any installation or technical queries you may have.

Once your Powerbox is installed no further adjustments will be required, as each one has four individually programmed fuel maps specifically for your make and model of car. The box is also extremely hard wearing, being shock resistant as well as waterproof but is traceless once removed, so it won’t interfere with your car’s warranty.
