Product Description


Improves torque & mpg!

The Power Box houses a digital microprocessor which intercepts the fuelling signals being transmitted from the ECU to the fuel pump; it then modifies them to ensure the exact amount of diesel required for enhanced performance. Such efficient use of the fuel optimises consumption, reduces smoke emissions and there is less engine stress, enhancing engine life in many cases.

The Power Box improves torque enabling the vehicle to change gears earlier and hold higher gears at lower speeds, making driving more pleasurable.

The unit fits using the original manufacturers plugs; these existing plugs are opened and the Power Box is secured in between.

Full fitting instructions are included with every unit.

Instant Improvement~!Review by Jay Butler
My 2006 Land Rover Discovery 3 TDV6 HSE, while well maintained with only 101,500 Kilometers just felt like it was 'suffering' when under load for over-landing. Having purchased from Devon 4x4 before, I gave their "PSI Power Tuning Chip" a crack and felt the difference instantaneously. The vehicle is more "sprightly" than ever before and now accelerates with ease. It drives more like a performance truck and not a tired old bus! Plus, it doesn't feel like the engine is being 'over-worked' either. Anyway, I'm very pleased with the product and would say, "purchase with confidence". Enjoy! (Posted on 30/08/2020)
