Seat is a Spanish carmaker from Barcelona, founded in 1950. On older Seat diesels, Stage 1 is a straightforward OBD job. TDI is Seat's turbo-diesel designation, shared with Volkswagen and Audi. The Seat diesel range is fully shared with VW on the MQB platform.
Within the VAG group, ECUs are standardised, so Seat files often work on VW/Audi/Skoda. The Seat community benefits from a large pool of Stage files drawn from the shared VAG catalogue. On Seat diesels, Stage 1 delivers a noticeable torque gain. The MQB platform is the most refined chip tuning segment in Europe. The Seat community in Southern Europe offers a large pool of ready-made Stage files. Mid-range Seat engines form the backbone of the range; Stage 1 preserves engine life.
DSG comes in dry- and wet-clutch versions. The DSG is VAG's signature dual-clutch gearbox, fitted to Seat. The DSG's TCU needs recalibration at Stage 1+.
