Citroen C5 2.2 HDI Stage 1 Remap

Name: Citroen C5 2.2 HDI Stage 1 Remap
Brand: Citroen

On Citroen C5 2.2 HDI diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.

How much bhp does Citroen C5 2.2 HDI chip tuning add?

It depends on the generation and the stock output. 2.2 HDI engines with 136–204 bhp reach 170–235 bhp with a Stage 1 remap; the largest gain is +34 bhp (2.2 HDI 136hp). Pick your version in the table below.

About the PSA 2.2 HDi / BlueHDi (four-cylinder common-rail diesel)

The 2.2 HDi is a four-cylinder common-rail diesel used in large cars such as the Peugeot 407/508/607 and Citroen C5/C6 and in vans such as the Jumper and Boxer. Some van versions come from the engine family developed jointly with Ford.

How a Stage 1 remap works on the Citroen C5 2.2 HDI

A Stage 1 remap recalibrates injection quantity, rail pressure and boost pressure; pull under load and on hills improves. On vans the torque is set with the gearbox and clutch limits in mind.

Pre-remap checklist

Injector leak-off test and rail pressure.
EGR valve and cooler; DPF (FAP) system and additive level.
Turbo play and boost leaks.
Dual-mass flywheel and clutch condition.

For commercial use the service history is always checked before the remap.

This section is based on GP Power ECU workshop experience; the power and torque figures come from the catalogue measurement above.

Frequently asked questions

How much bhp does Citroen C5 2.2 HDI chip tuning add?

It depends on the generation and the stock output. 2.2 HDI engines with 136–204 bhp reach 170–235 bhp with a Stage 1 remap; the largest gain is +34 bhp (2.2 HDI 136hp). Pick your version in the table below.

What is the difference between Stage 1 and Stage 2 on the Citroen C5 2.2 HDI?

Stage 1 is software only: no part of the car is changed and the figures in the table apply to this software. Stage 2 is software prepared for hardware changes such as the exhaust, intercooler or intake; the hardware comes first, then the software.

Will chip tuning damage the engine?

No. Values stay inside the safety margin the manufacturer leaves; engine, gearbox and turbo limits are not exceeded. Every file is verified with a road test and data logging. If the car needs maintenance first (worn injectors, blocked filter, weak clutch) we tell you before starting.

Will my fuel consumption go up?

With the same driving style it usually drops, because you hold the same speed at lower revs and less throttle. If you use the extra power, consumption naturally rises. It is down to your right foot.

How long does it take? Do I leave the car?

Most cars take 1–2 hours and you get the car back the same day; no need to leave it. Some models need the ECU removed, which takes longer — we tell you when booking.

Can I go back to stock later?

Yes. The original file is read and archived before any work. We restore the factory software free of charge whenever you ask.

What is checked on the Citroen C5 2.2 HDI before remapping?

Before working on the PSA 2.2 HDi / BlueHDi (four-cylinder common-rail diesel) we check: Injector leak-off test and rail pressure. EGR valve and cooler; DPF (FAP) system and additive level. Turbo play and boost leaks. Dual-mass flywheel and clutch condition. If something needs attention, maintenance comes first; the remap is applied to a healthy engine.
