A lot. The 1.6 TDI feels far stronger on the motorway and when overtaking. We tune SEATs across Bristol, North Somerset, Somerset and South Wales.
About this job
The results
This SEAT Leon 1.6 TDI now makes 145hp, up from 105hp as standard: 40hp more, an increase of around 38%.
Torque rose from 250Nm to 310Nm (+60Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.
What the work involved
Stage 1 is calibrated for a car with standard hardware. By refining boost, fuelling, timing and torque requests within the engine's safe limits, it delivers stronger, smoother acceleration and sharper throttle response.
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
