Save Fuel and Cut Costs: Remapping for Better MPG
Fuel prices keep rising, but a remap can help you squeeze more miles per gallon. Our Stage 1 tune often delivers up to 10% better MPG—while giving you smoother power delivery and fewer regeneration cycles.
Why Remapping Improves Economy
Factory ECU maps err on the side of rich mixtures for reliability and emissions. We:
- Refine injection timing to match your driving style.
- Adjust boost cut points to prevent over-fuelling.
- Reduce unnecessary regen events by smoothing airflow.
Real-World MPG Data
| Drive Type | Before | After |
|---|---|---|
| Motorway (70 mph) | 47 mpg | 52 mpg |
| Urban (stop/start) | 34 mpg | 38 mpg |
| Mixed Country | 40 mpg | 44 mpg |
Additional Tips to Boost MPG
- Keep tyres at manufacturer pressure for optimal roll resistance.
- Avoid heavy acceleration; use the torque band.
- Maintain regular DPF cleaning to prevent fuel over-enrichment.
- Use cruise control on steady stretches to stabilise consumption.
Cost Analysis
With current diesel at £1.60/litre, improving from 47 to 52 mpg on a 60-litre tank saves around £15–£20 per fill. Over a year (15,000 miles), that’s up to £200 saved.
