This is not a figure copied from a database. We hold a real before/after DynoRevolt sheet for the 3.0d — the 258 hp baseline and the Stage 1 result, measured in our own workshop, not estimated. Ask to see the run for your car.

BMW X4 Stage 1: 258 hp → 310 hp

Factory output for the BMW X4 3.0d is 258 hp and 560 Nm. A Stage 1 remap targets 310 hp and 650 Nm — 52 hp (+20%) and 90 Nm (+16%).

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 90 Nm shows up

On a diesel the useful change is torque, not peak power. Going from 560 Nm to 650 Nm fills in the mid-range, which is where a BMW X4 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, 258 hp to 310 hp, but you will feel the 90 Nm far more often than the 52 hp.

What Stage 1 involves on a BMW X4

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 258 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 310 hp and 650 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.
