Why diesels gain so much
Modern turbo diesels are heavily detuned from the factory for global markets and emissions margins. A careful remap recovers that headroom — typically a strong lift in torque low down, which is exactly where a diesel does its work. The result is a car that pulls harder in-gear and feels far more relaxed.
Performance or economy
You choose the priority. A performance map maximises power and torque; a fuel-optimise (Blue Optimize) map targets efficiency for high-mileage drivers; and our Merlin Blend sits in between for a useful lift that keeps economy in mind. We'll advise based on your mileage and how you use the vehicle.
Done properly
Every diesel remap starts with a diagnostic health check and a full backup of your original file. Files are developed and dyno-tested through the Viezu master tuner network and backed by an insurance-backed guarantee on remapping work.
