This is not a figure copied from a database. We hold a real before/after DynoRevolt sheet for the 2.0 JTDm — the 163 hp baseline and the Stage 1 result, measured in our own workshop, not estimated. Ask to see the run for your car.

Alfa Romeo Giulietta Stage 1: 163 hp → 207 hp

Factory output for the Alfa Romeo Giulietta 2.0 JTDm is 163 hp and 360 Nm. A Stage 1 remap targets 207 hp and 431 Nm — 44 hp (+27%) and 71 Nm (+20%).

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 44 hp changes on the road

A turbocharged petrol responds to a remap mostly through boost and ignition timing. Taking the 2.0 JTDm from 163 hp to 207 hp, with torque from 360 Nm to 431 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 (+27%) are normal for this kind of engine on pump fuel, with no hardware changes.

What Stage 1 involves on an Alfa Romeo Giulietta

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 163 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 207 hp and 431 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.
