Welcome to Miles Better!
We are specialists in engine eco-mapping that helps save money on diesel - up to 15%. Our diesel upgrades reduce your emissions too - which is better for the planet and helps meet your environmental targets.
The award-winning VIEZU Technology that we use has already been installed on over 24,000 vans for BT and 400 for Homeserve, as well as many other smaller fleets. BT subsequently made a reported saving of £4m a year and picked up the cost saving initiative award at the Fleet News Awards.
New technology makes engine mapping easy - with no mechanical intervention and no use of chemicals - the process if entirely green. We simply plug in a laptop to the vehicle’s ECU, take a reading and upgrade the files. It is fully insured with a 30 day money back guarantee.
We can also help you with bespoke power upgrades for both petrol and diesel vehicles.
Get in touch for free advice or an estimate. The VIEZU system is safe, fully insured and ISO approved, to give you total peace of mind.
If your diesel vehicle is more than five years old or has high mileage, we recommend you have an engine clean before we work on improving your fuel economy and engine performance, to ensure you get the maximum benefit. We can help to facilitate this work too if needed, by using our “Which?” approved engine cleaning partners.
