Car remapping prices in the UK range from £50 to £500+. But price alone doesn’t tell you much. Here’s what you’re actually paying for and what to watch out for.
Average UK Remap Prices (2026)
| Stage | Typical Price | What You Get |
|---|---|---|
| Stage 1 | £200-£350 | Software-only tune, +20-40% power |
| Stage 2 | £250-£450 | Tune for modified cars, +40-60% power |
| Stage 3 | £500+ | Built engine calibration, +60-100% power |
Why Prices Vary So Much
The cheapest remaps (£50-£100) are usually generic files downloaded from the internet. They’re not tailored to your car and can cause problems. A proper remap involves:
- Reading your specific ECU software version
- Custom calibration based on your car’s condition
- Diagnostic checks before and after
- Test drive to verify results
- Backup of your original file
Our Equipment
We use industry-leading tools for all our remapping work:
- Alientech — Professional ECU tuning and programming tools

Every remap file we create is custom-made for your specific vehicle — never generic, never off-the-shelf. We read your ECU’s original data, calibrate it for your car’s condition and your performance goals, then test and verify the results.

Is a Cheap Remap Worth It?
No. A £50 remap is a generic file that could damage your engine, fail your MOT, or cause transmission problems. The £100 you save could cost you thousands in repairs. Always choose a reputable tuner with proper equipment.
