Porsche 911 991 Stage 1: 520 hp → 676 hp
Factory output for the Porsche 911 991 3.8T Turbo is 520 hp and 660 Nm. A Stage 1 remap targets 676 hp and 891 Nm — 156 hp (+30%) and 231 Nm (+35%).
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 156 hp changes on the road
A turbocharged petrol responds to a remap mostly through boost and ignition timing. Taking the 3.8T Turbo from 520 hp to 676 hp, with torque from 660 Nm to 891 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 (+30%) are normal for this kind of engine on pump fuel, with no hardware changes.
What Stage 1 involves on a Porsche 911 991
We read the ECU, log the car as it stands, and put it on the dyno to confirm the 520 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 676 hp and 891 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.
