Alfa Romeo 156 Stage 1: 140 hp → 175 hp

Factory output for the Alfa Romeo 156 1.9 JTD is 140 hp and 305 Nm. A Stage 1 remap targets 175 hp and 380 Nm — 35 hp (+25%) and 75 Nm (+25%).

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 75 Nm shows up

On a diesel the useful change is torque, not peak power. Going from 305 Nm to 380 Nm fills in the mid-range, which is where an Alfa Romeo 156 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, 140 hp to 175 hp, but you will feel the 75 Nm far more often than the 35 hp.

What Stage 1 involves on an Alfa Romeo 156

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 140 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 175 hp and 380 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.
