Introduced here, Stage 1 mapping broadens the 2-litre turbo’s torque window while maintaining factory smoothness. Boost, load and ignition tables are refined for crisper low-gear response, yet cruising economy remains stock. Vmax restriction is lifted; all OBD monitors stay active for emissions checks. Cold-start, idle and part-throttle areas are recalibrated so the car drives OEM-clean but with added urgency when you lean on the pedal.
