Seat Leon Stage 1: 150 hp → 178 hp

Factory output for the Seat Leon 1.4 TSI is 150 hp and 250 Nm. A Stage 1 remap targets 178 hp and 326 Nm — 28 hp (+19%) and 76 Nm (+30%).

Those are the figures we work to on this engine. They are a starting point, not a promise: the number we hand back is the one your car makes on our dyno, measured before and after on the same day, in the same conditions.

What 28 hp changes on the road

A turbocharged petrol responds to a remap mostly through boost and ignition timing. Taking the 1.4 TSI from 150 hp to 178 hp, with torque from 250 Nm to 326 Nm, sharpens throttle response and shortens the gap between asking for power and getting it — the car stops feeling like it is thinking about it first.

Gains of this size (+19%) are normal for this kind of engine on pump fuel, with no hardware changes.

What Stage 1 involves on a Seat Leon

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 150 hp baseline — a tired or faulty engine gets diagnosed before it gets mapped, not after.

The calibration is written for your car, not pulled from a file library. We adjust fuelling, ignition timing and boost pressure, then re-run the dyno to verify the 178 hp and 326 Nm figure and check knock, lambda and temperatures under load.

Turnaround is same-day for most cars. Stock file is archived, so the car can go back to standard whenever you want.

Which Seat Leon this covers

These figures are for the 1.4 TSI as fitted 2017–2020. Engine code and ECU type decide what is possible, so send us the registration or VIN and we will confirm the exact variant before you book anything.
