Fiat Croma Stage 1: 200 hp → 241 hp

Factory output for the Fiat Croma 2.4 JTD is 200 hp and 400 Nm. A Stage 1 remap targets 241 hp and 486 Nm — 41 hp (+21%) and 86 Nm (+22%).

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 86 Nm shows up

On a diesel the useful change is torque, not peak power. Going from 400 Nm to 486 Nm fills in the mid-range, which is where a Fiat Croma 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, 200 hp to 241 hp, but you will feel the 86 Nm far more often than the 41 hp.

What Stage 1 involves on a Fiat Croma

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 200 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 241 hp and 486 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 Croma this covers

These figures are for the 2.4 JTD as fitted 2008 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.
