BMW · 330d · G20/F30 2015–present
The BMW 330d is one of the most satisfying diesel remaps on the market. The B57 engine delivers impressive economy alongside the power gains — making it the ideal executive cruiser upgrade.

Stage 1 & Stage 2
The same B57 block used in the 335d and 340d is fitted to the 330d, running at lower output. This means headroom is built into the hardware from day one. A remap brings it significantly closer to its faster siblings.
A Stage 1 remap on the BMW 330d requires no hardware modifications. Our specialist software recalibrates boost, fuelling and ignition timing within the engine’s safe limits, delivering instant, driveable gains you’ll feel from the first drive.
What Changes
Boost pressure, injection timing and fuelling are recalibrated on the B57. The result is +55hp and +100Nm, transforming motorway performance and overtaking ability without affecting everyday smoothness or economy.
Factory boost is set conservatively. We raise it to the level the turbo and internals can comfortably sustain, unlocking power that was always there.
Fuel delivery is recalibrated to match the new boost levels precisely — giving a cleaner burn, better response and improved efficiency under light loads.
Timing is advanced where the engine can safely benefit, improving combustion efficiency and delivering more torque across the full rev range.
The factory throttle map is deliberately muted. We sharpen it so the car responds the moment you press the pedal — no lag, no hesitation.
Common Questions
Pricing depends on the specific variant and stage. Contact us for a quote — we’re competitively priced and include a lifetime software warranty on every remap. Call 01792 732 062 or fill in the booking form.
A quality remap modifies the ECU’s calibration data rather than adding any external hardware. While a dealership with specialist equipment could detect a changed map, it leaves no physical trace and does not trigger warning lights.
Both options are available. Our workshop in Ammanford has a MAHA 4WD dyno for before/after verification. Our mobile technicians also cover the whole of South Wales and can come to your home or workplace.
A remapped 330d (320hp / 680Nm) produces more torque than a standard 335d (313hp / 630Nm) and is within touching distance on power — for a fraction of the price difference between the two cars.
In most cases yes — particularly on motorway runs. Better torque at lower revs means less throttle required, which can improve real-world fuel economy by 5–15%.
