AMG is the performance division of Mercedes (since 1967), building engines on the 'one man, one engine' principle in Affalterbach. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. Maybach is Mercedes's ultra-luxury sub-brand. On older Mercedes diesels, Stage 1 is flashed over OBD with no complications. Mercedes diesels are known for smooth, quiet running, a hallmark of the premium segment. Mercedes diesels have long been known for legendary reliability, with German taxi fleets running to million-kilometre mileages.
In the Mercedes commercial segment, Stage 1 focuses on torque. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. The Mercedes community is active in Europe, with a large pool of available Stage files. Mid-range Mercedes engines are a premium segment with a conservative factory calibration, and Stage 1 preserves engine life.
