BMW M5 Stage 1: 575 hp → 685 hp

Factory output for the BMW M5 Competition 44 V8 BI Turbo is 575 hp and 680 Nm. A Stage 1 remap targets 685 hp and 856 Nm — 110 hp (+19%) and 176 Nm (+26%).

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 110 hp changes on the road

A turbocharged petrol responds to a remap mostly through boost and ignition timing. Taking the M5 Competition 44 V8 BI Turbo from 575 hp to 685 hp, with torque from 680 Nm to 856 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 (+19%) are normal for this kind of engine on pump fuel, with no hardware changes.

What Stage 1 involves on a BMW M5

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 575 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 685 hp and 856 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.
