This is not a figure copied from a database. A 1.6 TDI of this exact power variant has been on our rollers, and we hold the DynoRevolt sheet for what it measured. Ask to see it. For before-and-after runs on the same machine, all 86 of ours are published in full on our dyno page — nobody else shows you theirs.

Seat Leon Stage 1: 116 hp → 145 hp

Factory output for the Seat Leon 1.6 TDI is 116 hp and 250 Nm. A Stage 1 remap targets 145 hp and 317 Nm — 29 hp (+25%) and 67 Nm (+27%).

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.

Where the 67 Nm shows up

On a diesel the useful change is torque, not peak power. Going from 250 Nm to 317 Nm fills in the mid-range, which is where a Seat Leon actually spends its time — pulling from 1,800 to 3,000 rpm in a high gear, overtaking without dropping two gears, towing or carrying weight without the engine falling on its face.

Peak power moves too, 116 hp to 145 hp, but you will feel the 67 Nm far more often than the 29 hp.

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 116 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, injection timing and boost, then re-run the dyno to verify the 145 hp and 317 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 1.6 TDI 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.
