Audi A3 RS3 2.5 TFSI Stage 1: 367hp → 420hp, 465→620Nm. Validated DMS calibration, proven on our dyno — not an off-the-shelf file. From €450. Athens +…
Audi A3 Stage 1: 367 hp → 420 hp
Factory output for the Audi A3 RS3 2.5 TFSI is 367 hp and 465 Nm. A Stage 1 remap targets 420 hp and 620 Nm — 53 hp (+14%) and 155 Nm (+33%).
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 53 hp changes on the road
A turbocharged petrol responds to a remap mostly through boost and ignition timing. Taking the RS3 2.5 TFSI from 367 hp to 420 hp, with torque from 465 Nm to 620 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 (+14%) are normal for this kind of engine on pump fuel, with no hardware changes.
What Stage 1 involves on an Audi A3
We read the ECU, log the car as it stands, and put it on the dyno to confirm the 367 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 420 hp and 620 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.
