Mercedes CLA (2016 - C117-X117) 220 (2.0T) 184 hp — premium petrol engine of the passenger segment of the Mercedes-Benz Group AG (Mercedes-Benz, AMG, Maybach, Smart, EQ) group (Германия, 1926). Stage 1 chip tuning raises power from 184 to 250 hp (+66 hp, +36%) and torque from 300 to 400 Nm (+100 Nm). ECU — Bosch MED17.7.2. Flashing method: OBD or Bench depending on the unit's protection.

Maybach is Mercedes's ultra-luxury sub-brand. Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). Mercedes encryption is among the toughest in the industry, especially on modern models. Maybach uses Mercedes engines for the ultra-luxury segment, with the emphasis on quietness and smoothness. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1.

Stage 1 on standard mid-range Mercedes petrol engines delivers a noticeable gain. 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.
