What an economy remap changes
Better MPG
Depending on the car you drive and how heavy your right foot is, economy tuning can improve your MPG by 5% to 30%. With fuel prices where they are, that adds up quickly over a year of commuting or a van's working week.
Fewer gear changes and easier towing
More torque low down means smoother acceleration up to cruising speed with fewer gear changes, and a trailer, caravan or full load feels lighter behind you.
Sharper throttle response
The car answers your right foot sooner. It's most noticeable on turbo diesels that suffer from turbo lag, because the extra low-down torque fills the gap before the turbo comes in.
No flat spots
A flat spot in the rev range makes a car feel hesitant just when you need it. By adjusting fuel delivery, boost and ignition timing, the remap smooths out the power band, so the engine pulls cleanly from low revs and overtaking or climbing hills takes less effort.
Lower running costs and emissions
An engine that works less hard to do the same job uses less fuel and puts less strain on itself, and an economy remap can help reduce your diesel's emissions too.
