BMW Series 3 Stage 1: 211 hp → 275 hp

Factory output for the BMW Series 3 325d is 211 hp and 450 Nm. A Stage 1 remap targets 275 hp and 504 Nm — 64 hp (+30%) and 54 Nm (+12%).

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 54 Nm shows up

On a diesel the useful change is torque, not peak power. Going from 450 Nm to 504 Nm fills in the mid-range, which is where a BMW Series 3 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, 211 hp to 275 hp, but you will feel the 54 Nm far more often than the 64 hp.

What Stage 1 involves on a BMW Series 3

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 211 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 275 hp and 504 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.

Which BMW Series 3 this covers

These figures are for the 325d as fitted 2015–2019. Engine code and ECU type decide what is possible, so send us the registration or VIN and we will confirm the exact variant before you book anything.
