Frequently Asked Questions
What does an ECU remap do on the Citroën DS4 1.6 THP 165hp ( 165 PS / 121 kW )?
An ECU remap (chiptuning) modifies the engine control unit software to optimise parameters like injection timing, turbo boost pressure and fuel delivery. On the 1.6 THP 165hp ( 165 PS / 121 kW ), this typically results in more power, better throttle response and improved fuel efficiency at part load.
How much power gain is possible with Stage 1 on the 1.6 THP 165hp ( 165 PS / 121 kW )?
Stage 1 brings the 1.6 THP 165hp ( 165 PS / 121 kW ) from 165 PS to 183 PS — a gain of +18 PS. No hardware modifications are required, making it the most popular and cost-effective tuning option.
Is chiptuning reversible on the Citroën DS4?
Yes. We always save the original ECU file before applying any remap. The tuning can be fully reversed to factory settings at any time.
