SEAT Leon (1P) 2005-2012 2.0 TFSI 261bhp remap figures

Who is the Stage 1 map for?

• Drivers who want a noticeably quicker car from a software-only change, with no new parts.
• Daily drivers who want stronger mid-range pull and a sharper throttle.
• Anyone who wants the biggest gain we list without fitting hardware.

What this means for your Leon

On a turbocharged petrol engine a remap adjusts boost, ignition timing and fuelling together, so both power and mid-range torque rise and the car pulls harder out of corners and junctions.

This car is listed with a Bosch ME9.1 engine control unit. Older engine management is simpler to work with, but age matters: worn sensors, leaks and tired components can hold back what a remap delivers, which is why we run a diagnostic check first.

We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.

Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.
