Diesel Tuning Boxes for Improved Performance and Economy

If you want to save money on fuel bills and increase performance with a product that doesn’t need a specialist mechanic to fit, then a diesel tuning box is a perfect solution. Our tuning boxes can typically be fitted at home in less than 10 minutes and offer instant gains from the moment you start driving.

Why Buy A Diesel Tuning Box?

Your diesel engine can be tuned to safely produce more power and torque to its original factory settings. Why is this? Car manufacturers build their vehicles to one global specification that reduces production costs and enables them to function consistently across different environments, conditions and user requirements.

Examples of this are; suspension systems that offer composed road holding on a motorway whilst withstanding potholes on a farm track; Air conditioning systems that can keep drivers comfortable in the Australian Outback or Alaska; Engines that can run on fuel supplies available in London or Nairobi.

In order to run on varying global fuel quality, engines have restrictions applied to their ECU to decrease/limit power which enables consistent running but creates a disadvantage for drivers who are guaranteed high quality fuel. This is where the use of diesel tuning technology can transform your diesel engine.

At TDI Tuning, our tuning boxes are designed to increase power by plugging into the engine and streamlining the fuel injection and turbo boost parameters. This includes the timing, pressure and quantity of fuel added. It results in significant improvements in your engine’s overall performance, both in terms of power and torque which enables the engine to operate in higher, more fuel efficient gears for longer, directly improving fuel economy.
