More Performance


Every driver wants their diesel vehicle to perform at its best while saving money on fuel costs. Our diesel remaps are tailored to achieve both!

By making adjustments to the vehicle’s Engine Control Unit, we can optimise several parameters such as fuel injection timing, turbo boost pressure, and air-to-fuel ratios. These modifications result in increased power, greater torque, sharper throttle response, and smoother power delivery, making your vehicle more responsive and enjoyable to drive.

Another key benefit of our diesel remaps is improved fuel economy, too. By optimising engine performance, you can achieve significant fuel savings. More torque means fewer gear shifts and reduced throttle pedal movements, resulting in better mpg and lower fuel consumption.

Enjoy increased performance and lower fuel costs, book a MET remap today!
