About this job

The results

Power went from 231hp to 290hp, an increase of 59hp or around 26%.

Torque rose from 540Nm to 600Nm (+60Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

A Stage 1 remap is a software calibration for an otherwise standard car. We refine parameters such as boost, fuelling, ignition timing and torque limits within safe margins, so it pulls harder through the mid-range without any hardware changes.

We also tuned the gearbox, raising its torque limits to match the engine and making shifts quicker and more decisive, particularly in Sport and manual modes.

How we carried it out

  • Diagnostic scan for stored faults before any work
  • Stabilised power supply connected while programming
  • Original software read and saved, so the car can be returned to standard
  • Calibration written, then the car checked again afterwards

Thinking about the same for your Mercedes-Benz?

We come to you from our Weston-super-Mare base, across Bristol, Somerset, Gloucestershire, Wiltshire, South Wales and parts of Devon and Dorset. Results depend on the exact car, so we confirm what suits yours before quoting.
