Mercedes Benz remapping at Regal Tuning

Verified gains, engine by engine

Every Mercedes Benz calibration in this database is software-only Stage 1 upwards: no hardware changes, fully reversible, and developed against the specific engine variant rather than a generic map. Each vehicle page lists the exact factory output alongside the tuned figures for that engine and generation.

Figures depend on vehicle health, fuel quality and conditions — we confirm the expected output for your specific vehicle in writing before any work begins. If your exact variant isn't listed, ask us: coverage expands continuously.
