Citröen Remapping Service

A Citroën remap makes a comfortable car easier to drive: more pull when you join the motorway, fewer gear changes on hills and, driven gently, better fuel economy. The map is written in-house for your car by a qualified motorsport engineer.

Why Remap Your Citroën?

Citroëns are built for comfort, and a remap keeps it that way while taking away the strain a small engine can feel with a full car or a loaded van. You get a smoother, stronger drive from a map written for your car. If fuel is what matters most, our economy remapping puts the gain there.

Citroën Diesel Tuning

The HDi and BlueHDi diesels in the Berlingo, C4 and C5 Aircross pick up more torque low down, so overtaking takes less planning. Berlingo, Dispatch and Relay owners who use the van for work will find more on our van remapping page.

Citroën Petrol Engine Tuning

The 1.2 PureTech in the C3, C4 and C5 Aircross feels livelier off the line and pulls harder in the mid-range after a remap. Automatic cars can have the gearbox looked at too through our DSG and TCU remapping.

Pick your Citroën in the Remap Calculator above to see the figures for your engine, or ring us on 087 744 2633. We also do car diagnostics if a warning light is what brought you here.

What happens on the day

Check your Citroën in the Remap Calculator or give us a call, then book it in. On the day it goes on our 4WD dyno for a before run, the map is written for your engine, and an after run shows you the difference in power and torque.

If your Citroën is an automatic, ask us about a gearbox (TCU) remap on the same visit.

Citroën remap questions

Book Your Remap

What will my Citroën make after a remap?

Pick your model, year and engine in the Remap Calculator for the standard and remapped figures. On the day, the dyno shows what your own car makes before and after.

Can you remap the gearbox on an automatic Citroën?

Yes. Ask us about a gearbox (TCU) remap on the same visit, for quicker shifts and room for the extra torque.

How do I book my Citroën in?
