SEAT Leon 1.4 TSI 125hp Stage 1 Calibration
This SEAT Leon 1.4 TSI went from 125hp and 200Nm to 155hp and 270Nm with our Stage 1 ECU calibration, a gain of 30hp and 70Nm.
Why remap a Leon 1.4 TSI?
The Leon 1.4 TSI balances practicality and economy well, and Stage 1 makes it noticeably stronger throughout the rev range. Throttle response improves, there is more mid-range torque and power delivery is smoother, so it feels far more responsive in everyday driving with factory-like refinement.
