Citroen DS4 1.6 THP 155HP 2011-2015

Remapping Data - Engine Remap Performance and Torque Gains

Remapping the Citroen DS4 (2011-2015), 1.6 THP 155HP.

The Citroen DS4 (2011-2015)'s 1.6 THP 155HP sees a torque-led Stage 1 remap: pulling power climbs 29.2% to 310Nm, well ahead of the 22.6% rise in BHP from 155 to 190.

Turbocharged petrol engines have plenty of scope for a Stage 1 remap, and this transformative improvement is best felt through sharper throttle response across the rev range. These figures apply to 2011-2015 models.

  • Power: 155bhp standard, 190bhp after a Stage 1 remap.
  • Torque: 240Nm standard, 310Nm after a Stage 1 remap.
  • This is a torque-led gain: pulling power increases by more than BHP, which is felt mainly as a stronger mid-range.
  • This is a turbocharged engine, which typically means further headroom exists beyond Stage 1 if hardware is upgraded.
  • As a petrol engine, the practical benefit is mainly felt as sharper throttle response and a broader power band.
  • These figures apply specifically to 2011-2015 models.
  • These are Stage 1 figures only, achieved without any hardware changes.

Questions about remapping your DS4 1.6 THP 155HP

How much power and torque does a Stage 1 remap add to the Citroen DS4 (2011-2015) 1.6 THP 155HP?

A Stage 1 remap typically takes the Citroen DS4 (2011-2015) 1.6 THP 155HP from 155bhp to around 190bhp, and torque from 240Nm to around 310Nm. This is a transformative gain achieved entirely through software, with no hardware changes required.

Is the Citroen DS4 (2011-2015) 1.6 THP 155HP a good candidate for remapping?

Generally, yes: as a turbocharged engine it has the headroom to respond well to a quality remap, and the transformative gain shown here reflects that. The main caveats are condition, not the engine itself, a healthy service history, no outstanding fault codes, and (for diesels) a clear DPF and EGR are what actually determine whether this particular car is ready for a remap.

Will remapping affect the warranty on my Citroen DS4 (2011-2015)?

A manufacturer can only void the parts of a warranty that the remap directly affects, not the entire vehicle, under the Consumer Rights Act and EU Block Exemption principles. In practice, on a Citroen DS4 (2011-2015) 1.6 THP 155HP this usually means engine and transmission-related claims are the ones worth discussing with a reputable tuner before booking.

What should I check before booking a remap for my Citroen DS4 (2011-2015) 1.6 THP 155HP?

Before booking, confirm the tuner uses a custom or bespoke file rather than a generic off-the-shelf map, ask whether they do a pre-remap health check, and check service history and mileage on your specific Citroen DS4 (2011-2015).

What's the difference between a Stage 1 and Stage 2 remap for the 1.6 THP 155HP?

Stage 1 is software-only and is what the figures on this page reflect. Stage 2 builds on that, but on a turbocharged engine like this, Stage 2 usually adds further gains but requires supporting hardware such as an upgraded intake or exhaust, so it is a separate conversation with a tuner rather than an automatic next step.

Will remapping my Citroen DS4 (2011-2015) affect my insurance?

Yes, always, a remap is a modification and must be declared to your insurer regardless of size. Given this transformative gain on the 1.6 THP 155HP, expect a likely premium increase, and it is worth getting a quote from a specialist modified-vehicle insurer before booking the remap itself.
