Another BMW F-Series diesel refined properly. This BMW 118d 2.0 — the B47 turbo diesel — came in for our Stage 1 custom dyno calibration, developed live on our 4WD linked V-Tech dyno.
It arrived producing 150bhp and 328Nm on our baseline run. After a bespoke calibration written for this exact car, it left making 193bhp and 423Nm — measured on the rollers, not estimated:
| Measurement | Stock | DC Stage 1 Custom |
|---|---|---|
| Engine power | 150.3 hp @ 3,879rpm | 193.7 hp @ 3,742rpm |
| Engine torque | 328 Nm @ 2,386rpm | 423 Nm @ 2,347rpm |
| Wheel power | 127.6 hp @ 3,537rpm | 170.9 hp @ 3,742rpm |
That’s +43bhp and +95Nm, and the focus here was everyday drivability. Stronger mid-range torque, sharper throttle response and a far more responsive feel in normal driving — the 118d finally pulls the way it always should have, without any drama.
“Unbelievable. I will recommend you every time.”
— 118d owner, verified customer
