Custom Dyno Tune & xHP Gearbox Software
The N57 30d is one of BMW's most capable diesel engines, but it leaves significant performance on the table from the factory. Our custom live dyno calibration transforms it into a genuinely rapid machine.
The Platform
The 3.0-litre straight-six single turbo diesel controlled by the Bosch ECU, paired with the ZF8 automatic transmission. BMW quotes 258bhp and 560Nm, on our 4WD dyno we typically see 250–260bhp and 550–560Nm from stock.
Tuning Options
All remaps are built live on our 4WD linked rolling road, custom-calibrated to your exact car on the day, not a generic file from a database.
Best Value Package
The most popular combination we offer. ECU and gearbox tuned together as one synchronised system, delivering a driving experience that neither can achieve alone.

Compatible with ZF8 automatic gearboxes across the entire BMW 30d range. From £299 inc. VAT. Best results when combined with a Stage 1 ECU remap.
