ECU Remapping
ECU remapping is the process of adjusting your engine’s control software to improve how it performs. By modifying parameters like fuel delivery, boost pressure and torque limits, we can unlock more power, smoother acceleration and better fuel economy, all without changing any physical parts.
Want more power or better MPG without hardware changes? ECU remapping delivers exactly that.
Great service. Jim was very helpful and friendly. He got my van in very quickly, understanding that I can’t work without it. The engineer (also called Jim) was very thorough and professional. Top service; I would highly recommend them.

Great service today from Shrewsbury Remapping. Arrived exactly as arranged. Very friendly mapper, fixed my Adblue issue, another fault came on the auto stop/start after the fix, which was also solved before he left. He made sure I was happy before he left and let me know that any issues in future they will come out and resolve them.

Had the dpf issues sorted on the van and they did a great job. Not stuck in limp mode anymore either which I’m really happy about.

No exaggeration, but is I could at least double the review stars to ten, it would still not be enough.
My van is my work horse and without it, no business.
The DPF was playing up and by Thursday 12th it really put my van out of action.
I text this company and by the next day, it was in their hands.
They put themselves out in order to get me back on the road and by 18th the Van ran like a dream, no really… it did.
I’m so pleased I found them and can absolutely recommend.
Thank you
