About this job
The results
From 150hp as standard to 175hp, the Seat Leon 1.4 TSI gained 25hp, roughly 17% more power.
Torque rose from 250Nm to 320Nm (+70Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.
What the work involved
This was a Stage 1 calibration: no hardware changes, just carefully refined engine software. Boost, fuelling, timing and torque limits are adjusted within safe margins for more usable performance every day.
How we carried it out
- Diagnostic scan for stored faults before any work
- Stabilised power supply connected while programming
- Original software read and saved, so the car can be returned to standard
- Calibration written, then the car checked again afterwards
