economy remapping, in particular, can improve fuel economy by up to 15%. This is because the engine is able to run at a more efficient operating point, which leads to less fuel consumption. The power band is also expanded, which means that the engine produces more power at lower revs.

For drivers who are more serious about achieving the best MPG possible, you can go further with a dedicated fuel economy tune using an HP Tuners interface. This highly effective method provides even better (and more consistent) MPG which ultimately saves you more time and money otherwise spent at the pump.

After remapping, your car's major components, such as the clutch, may suffer greater wear and tear. And you may need to buy higher octane fuel, which is usually more expensive.

By fine-tuning these parameters, ECU remapping can unlock the hidden potential of the engine, resulting in increased power, improved fuel efficiency, and enhanced driving dynamics.
