Performance Tuning – Standish, near Wigan

S&R Miller is your go-to destination for Audi and Volkswagen ECU remapping and performance tuning across the North West of England.

Our skilled technicians live and breathe VW Group engineering, using cutting-edge calibration tools and data-logging to unlock safe, reliable gains from your engine.

Every driver is different, so every map and upgrade we create is bespoke. After an initial health check and diagnostics, we tailor the calibration to your goals—whether that’s stronger mid-range torque, quicker throttle response, smoother drivability, or improved fuel efficiency on motorway runs. We focus on OEM+ refinement: power where you feel it most, while protecting engine and drivetrain components.

We offer staged tunes (e.g. Stage 1/2) for popular petrol and diesel models, plus DSG/TCU optimisation for a more responsive, cohesive driving experience. Where applicable, we keep within sensible thermal and mechanical limits and do not remove or disable emissions controls, helping you stay road-legal.

You’ll get clear before/after data, a thorough road test, and the option to revert to original if required. Whether you want a spirited daily, a towing upgrade, or an eco-minded tune, S&R Miller has you covered—delivering performance you can feel, confidence you can trust.
