Volkswagen Polo (2005 - 9N3) 1.8 T 180 hp — mass-market petrol engine of the passenger segment of the Volkswagen Group (VAG) — материнская компания group (Германия, 1937). Stage 1 chip tuning raises power from 180 to 210 hp (+30 hp, +17%) and torque from 225 to 280 Nm (+55 Nm). ECU — Bosch ME7.5. Flashing method: OBD or Bench depending on the unit's protection. A petrol engine built in 2005 — the era before widespread firmware encryption, OBD flash without complications.

VAG is Europe's largest automotive group by production volume. Volkswagen is Germany's largest carmaker, founded in 1937 in Wolfsburg. GTI and R are Volkswagen's performance sub-brands. TGI is VW's designation for natural-gas (CNG) engines. TSI is Volkswagen's badge for direct-injection turbo-petrol engines. VW shares its ECUs and calibration algorithms with Audi.

Stage 1 on stock mid-range VW petrol engines gives a noticeable gain. The VW community is renowned for its active tuning scene and a huge library of available Stage files. ECUs are standardised across VAG, so a single file often fits a dozen different models. The VW community offers a large library of ready-made Stage files for mainstream models. The factory calibration is conservative, with headroom for Stage 1 and no hardware changes. The MQB platform is the most refined chip tuning segment in Europe. Mid-range VW engines form the core of the range and take Stage 1 with reliability fully preserved.
