We love French beauties. Whenever DS cars make their appearance, they leave us with a big smile. Specially of the HDI kind because there is so much power to gain, even on a Stage1 ECU remap. On completely stock hardware these cars can behave so much better than stock, it is hard to believe. The engine inside this Citroen DS4 is 1.6 HDI 120hp, following Euro6 emission standards which are amongst the strictest that exist, only replaced by Euro6.2 just recently. Everything was kept stock on the car with the exception of an upgraded K&N air filter inside the stock filter box.
With the stock map it made 120hp on our dyno, engine power. With our custom Stage1 ECU remap, power reached 146hp with a big torque gain! Driving the car on the road feels much more lively and accelerates very easily even in high gear.
