Stage 1 chip tuning raises power from 125 to 155 hp (+30 hp, +24%) and torque from 200 to 250 Nm (+50 Nm). ECU — Bosch MED17.2.5. Flashing method: OBD or Bench depending on the unit's protection. TCU units on this engine: Temic DQ200 (MQB), Temic DQ200G2 — each is calibrated with a separate file (torque limiter, shift maps for Stage 1). In the CHIPOK database: 3 configurations · 3 ECU variants. A petrol engine built in 2015 — a Tricore platform without strong protection; OBD access works.
'Volkswagen' literally means 'the people's car' — the original philosophy of mass affordability. DSG is the VAG group's proprietary automated gearbox, developed by Volkswagen. TSI / TDI / TGI are VW's badges for petrol / diesel / natural-gas engines respectively. GTI is Volkswagen's performance range dating from 1976. Mid-range VW turbo-petrol engines are a high-volume Stage 1 subject. The VW community is one of the most open in Europe, with a large library of ready-made Stage files.
ECUs are standardised across VAG, so a single file often fits a dozen different models. 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. 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.
DSG comes in dry- and wet-clutch versions with different torque classes. Tiptronic is VW's classic torque-converter automatic for longitudinal engines. DSG (Direct Shift Gearbox) is VW's proprietary dual-clutch automated gearbox.
