Fiat Grande Punto Stage 1: 75 hp → 98 hp

Factory output for the Fiat Grande Punto 1.3 JTD is 75 hp and 190 Nm. A Stage 1 remap targets 98 hp and 245 Nm — 23 hp (+31%) and 55 Nm (+29%).

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 55 Nm shows up

On a diesel the useful change is torque, not peak power. Going from 190 Nm to 245 Nm fills in the mid-range, which is where a Fiat Grande Punto 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, 75 hp to 98 hp, but you will feel the 55 Nm far more often than the 23 hp.

What Stage 1 involves on a Fiat Grande Punto

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 75 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 98 hp and 245 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 Fiat Grande Punto this covers

These figures are for the 1.3 JTD as fitted 2005 onwards. 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.
