BMW 320d tuning

BMW 320d remapping in Bristol, Somerset and South Wales

The 320d is one of the most popular cars in the UK, and a remap gives it stronger, smoother torque for motorway driving and overtaking. We come to you from our Weston-super-Mare base, across Bristol, Somerset, Gloucestershire, Wiltshire, South Wales and parts of Devon and Dorset.

What a remap does on the 320d

The 320d's extra torque after a remap makes it more relaxed on the motorway and far stronger when overtaking. A 320d we tuned with a gearbox tune went from 184hp to 220hp.

Economy-focused calibrations are popular with high-mileage drivers.

Gearbox tuning

The ZF 8-speed is mapped for smoother, quicker shifts and to make the best use of the extra torque.

Common questions

Will a remap help my 320d's economy?

It can. Economy-focused tunes give more torque low down, so the engine works less hard. Results depend on how and where you drive.

Do you tune the 318d too?

Yes. A 318d we tuned went from 150hp to 190hp.
