Citroen C4 2.0 HDI 150 Stage 1 Remap (190 BHP | 420 Nm)

The Citroen C4 2.0 HDI 150 BHP model comes equipped with the DW10DTED4 Euro 5 engine. Though it offers acceptable torque and power straight from the manufacturer, in larger vehicles, it might feel slightly underwhelming. The silver lining is that this 150BHP engine is identical to the more powerful 163BHP DW10CTED4. They share the same turbo and injectors, with the only distinction being the ECU software.

This is excellent news because a straightforward remap can yield significant (and entirely safe) boosts in power.

The remap for the Citroen C4 2.0 HDI 150 engine, crafted in house by our expert HDI Tuning development engineer, is unparalleled. The HDI Tuning Stage 1 Remap elevates peak power to 190BHP and boosts mid-range torque to an impressive 420Nm. Our remap is designed for both outstanding power and reliability, crucial for your daily drive.

Post-remap, torque delivery is smooth, consistent, and exhilarating. You’ll notice the car’s improved pull, and after adjusting to the extra power, you’ll even see a slight increase in fuel efficiency during regular driving.

For those with an Auto gearbox, rest assured that the full torque Stage 1 remap is safe. If preferred, we can modify it for slightly reduced torque.

Citroen C4 2.0 HDI 150 Stage 2 Remap with Performance Exhaust (210 BHP | 440 Nm)

The Stage 2 remap for the Citroen C4 2.0 HDI 150 engine was designed to run with an intercooler upgrade, and a free-flowing straight through style exhaust system. This remap delivers some extra top end power for those looking for that little bit extra. The exhaust work is important for this higher power remap, you likely won’t achieve the full power of this stage 2 remap without the additional exhaust work. It’s an option to increase the exhaust bore from the DPF onwards or to use a sports DPF and this will keep the vehicle road legal. With 440Nm of torque and 210+ BHP you’re going to notice a big performance gain when running this remap.
