Mercedes-AMG SLK55 Stage 2

A Stage 2 calibration for an SLK55 AMG must be tied to the exact generation, engine and fitted hardware. Naturally aspirated AMG engines respond differently from turbocharged cars, so credible advice starts with the specification rather than a dramatic generic gain.

Mercedes-AMG SLK55 Stage 2

This Mercedes-AMG SLK55 went from 360hp and 510Nm to 395hp and 550Nm with our Stage 2 calibration, a gain of 35hp and 40Nm.

Add-ons

  • Speed limiter solution
  • O2 solution

Advanced dealer-level diagnostics were included before and after the tune.

Can you tune a naturally aspirated AMG V8?

Yes. Gains are smaller than on turbo engines, but the V8 responds sharper and pulls harder. We come to you across Bristol, North Somerset, Somerset and South Wales.

About this job

The results

Power went from 360hp to 395hp, an increase of 35hp or around 10%.

Torque rose from 510Nm to 550Nm (+40Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

This was a Stage 2 calibration, written for a car with supporting hardware such as intake, intercooler or exhaust upgrades. With the engine breathing more freely, the software can safely ask more of it than a Stage 1 map.

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.

Common questions

Will a naturally aspirated SLK55 gain as much as a turbo car?

Generally no. Without forced induction, software-only peak gains are typically more limited, so results must be based on the exact engine and modifications.

Is a gearbox tune always included?

No. Engine and gearbox programming are separate services. Compatibility and the benefit of each are assessed for the specific SLK55.
