About this job
The results
Power went from 184hp to 220hp, an increase of 36hp or around 20%.
Torque rose from 380Nm to 440Nm (+60Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.
What the work involved
A Stage 1 remap is a software calibration for an otherwise standard car. We refine parameters such as boost, fuelling, ignition timing and torque limits within safe margins, so it pulls harder through the mid-range without any hardware changes.
How we carried it out
- Diagnostic scan for stored faults before any work
- Stabilised power supply connected while programming
- Original software read and saved, so the car can be returned to standard
- Calibration written, then the car checked again afterwards
Thinking about the same for your BMW?
We come to you from our Weston-super-Mare base, across Bristol, Somerset, Gloucestershire, Wiltshire, South Wales and parts of Devon and Dorset. Results depend on the exact car, so we confirm what suits yours before quoting.

- Dealer-level diagnostics before and after
- Fully mobile, at home or work
- Lifetime software warranty and support
- 14-day money-back guarantee
