Another modern BMW petrol optimised properly. This BMW 320i G20 — running the B48 2.0 turbo petrol — came in for our Stage 1 custom dyno calibration and left completely transformed, every bit of it developed live on our 4WD linked V-Tech dyno.
It arrived producing 172bhp and 298Nm on our baseline run. After a bespoke calibration written for this exact car, it left making 277bhp and 417Nm — measured on the rollers, not estimated:
| Measurement | Stock | DC Stage 1 Custom |
|---|---|---|
| Engine power | 171.9 hp @ 4,525rpm | 277.6 hp @ 6,171rpm |
| Engine torque | 298 Nm @ 3,224rpm | 417 Nm @ 3,750rpm |
| Wheel power | 144.2 hp @ 4,434rpm | 239.3 hp @ 5,907rpm |
That’s +106bhp and +119Nm, and the difference is significant. The engine now delivers far stronger mid-range performance, sharper throttle response and a much more urgent pull through the gears — completely changing how the car feels in real-world driving, while keeping delivery smooth and progressive.
The B48 platform responds exceptionally well when calibrated correctly. That headroom lets us safely unlock a substantial increase in performance while maintaining smooth power delivery and everyday reliability — provided the map is written properly for the specific car, not flashed from a generic file.
All work was carried out live on our V-Tech 4WD linked dyno, with a full health check before any tuning and detailed data logging throughout to ensure safe, consistent and repeatable results. The calibration was written for this exact car — its ECU variant, its fuel, its condition. No generic files. No shortcuts. Just precision tuning done properly, with the original software backed up so it’s fully reversible.
