Volkswagen Transporter / Multivan (1996 - T4) 2.5 115 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 115 to 125 hp (+10 hp, +9%) and torque from 200 to 215 Nm (+15 Nm). A petrol engine built in 1996 — the era before widespread firmware encryption, OBD flash without complications.

The VW community is one of the most active in the world for chip tuning. The ID line is VW's dedicated series of all-electric models. VAG is Europe's largest automotive group by production volume. On older-generation VW petrol engines, Stage 1 is flashed via OBD without a bench. The factory calibration on VW petrol engines is conservative, leaving headroom for Stage 1. TGI is VW's designation for natural-gas (CNG) engines.

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 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.
