The DTUK® ECO 3 Maximum Economy Improves Fuel Economy
With the rise in fuel prices and concerns over environmental issues we're all looking for something that improves fuel economy. The rise in diesel car sales goes to show a shift toward more economical cars, so we're on the right track.
Let's say you've discovered your Ford Focus TDCI has poor fuel economy. You're confined to manufacturer specifications goverened by strict emissions regulations and tax bands, so your Ford Focus fuel economy isn't going to improve. Or is it?
Can we do something to improve diesel mpg?
Well, the good news is you can improve your diesel fuel economy and reduce your carbon footprint with our ECO 3 Maximum Economy Digital Diesel Tuning System. The "Green Box" is designed to ensure your diesel engine runs much more smoothly, efficiently, and because the right amount of fuel is running through your system reduces emissions.

- Driving between 30-50mph - 10% Improvement
