Economy remapping for diesels

Make the same journey cost less. On a diesel, an economy remap is usually worth 5 to 15 percent better mpg, as long as you drive the same way afterwards.

  • Usually 5 to 15% better mpg on diesels
  • Proven on our own rolling road
  • 30-day money-back guarantee
Straight answers

Is it worth it on your car?

Diesel

Usually 5 to 15 percent better mpg, if you drive the car the same way. Drive it harder and you'll spend the saving rather than bank it.

Petrol

Very little. Economy tuning doesn't achieve much on a petrol engine, and we'd rather tell you that than take the booking.

Vans and motorhomes

Working diesels that carry weight often gain the most, because the engine works less hard for the same load.

Why it works

Why your car isn't already set up for economy

Manufacturers ship one set of maps worldwide. The same file has to cope with different climates, altitudes and fuel quality, so it's written to work anywhere rather than to suit your car and your roads.

An economy remap recalibrates fuelling, boost and torque delivery so the engine does the same work with less throttle. It's written for your exact engine and checked on our 4WD rolling road.

  • Software only: emissions equipment stays fitted and working
  • Software support for the life of the car
  • Covered by our 30-day money-back guarantee

Questions

Common questions

How much fuel will I save?

On a diesel, usually 5 to 15 percent, as long as you drive the same way afterwards. On a petrol, very little.

Will it remove my DPF or EGR?

No. It's software only, and we don't remove or disable emissions equipment as part of an economy remap.

What if I don't like it?

Economy remapping is Stage 1 tuning, so it's covered by our 30-day money-back guarantee. We put your original file back and refund the tuning.

Will I lose power?

No. Most drivers find the car feels stronger lower down, because there's more torque where you use it.
