Citroen DS4 1.6 THP Stage 1 Remap

Name: Citroen DS4 1.6 THP Stage 1 Remap
Brand: Citroen

On Citroen DS4 1.6 THP turbo petrol engines a Stage 1 remap recalibrates the boost pressure, ignition timing, fuelling 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 DS4 1.6 THP chip tuning add?

It depends on the generation and the stock output. 1.6 THP engines with 155–210 bhp reach 190–240 bhp with a Stage 1 remap; the largest gain is +40 bhp (1.6 THP 200hp). Pick your version in the table below.

About the PSA / BMW 1.6 THP (Prince)

The 1.6 THP is the turbo petrol engine developed jointly by Peugeot and BMW, used in the Peugeot 207, 308, 3008, RCZ, Citroën DS3, DS4, C4 and Mini Cooper S from 150 to 270 hp.

How a Stage 1 remap works on the Citroen DS4 1.6 THP

Stage 1 recalibrates boost, ignition and fuelling within the limits of the original hardware. The twin-scroll turbo responds quickly and the gain spreads across the rev range. Knock-sensor data and fuel quality are decisive in the calibration.

Pre-remap checklist

Timing chain and tensioner (a known issue on early generations).
Carbon build-up on the intake valves (direct injection).
High-pressure fuel pump and ignition coils.
Oil consumption and the PCV system.

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 DS4 1.6 THP chip tuning add?

It depends on the generation and the stock output. 1.6 THP engines with 155–210 bhp reach 190–240 bhp with a Stage 1 remap; the largest gain is +40 bhp (1.6 THP 200hp). Pick your version in the table below.

What is the difference between Stage 1 and Stage 2 on the Citroen DS4 1.6 THP?

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 DS4 1.6 THP before remapping?

Before working on the PSA / BMW 1.6 THP (Prince) we check: Timing chain and tensioner (a known issue on early generations). Carbon build-up on the intake valves (direct injection). High-pressure fuel pump and ignition coils. Oil consumption and the PCV system. If something needs attention, maintenance comes first; the remap is applied to a healthy engine.
