What an economy map changes

Torque delivery, injection timing and boost strategies are refined to reduce throttle input at cruise and in urban driving, improving efficiency.

Realistic fuel economy gains

Typical gains are 5–15% depending on vehicle, routes and driving style. Smooth throttle and steady speeds help the most.

DPF health matters

Short, cold trips and poor fuel quality hurt DPF longevity. Allow full regens, use quality diesel and keep sensors/thermostats healthy.

Warning signs & good habits

Rising regen frequency or oil dilution — ask us to review logs.

Keep tyres at correct pressures; rolling resistance hurts MPG.

Service on time — fresh oil, filters and a healthy thermostat.
