Citroen C4 VTS 1.6T utilises an EP6-DT engine that produces 150bhp at the flywheel.

Citroen DS5 1.6T THP163 with a JCW hybrid turbo and Etuners stage4 ECU remap
The Citroen DS5 1.6T usually comes with an EGS automatic gearbox and the Euro5 version of THP engines – THP163.

This tiny 1.4 HDI70 engine is a downscaled version of the very successful 1.6 HDI and is usually found on the Citroen C3 and Peugeot 208. Other models use it too, but on the heavier platforms like the C4 and 308 it is no fun at all, due to the increased weight of the car.

PCV delete – why do it? One of the most discussed and debated modifications on THP/N14 engines is deleting the rear PCV system. THP200 has this by default, but all smaller THP variants use the PCV system in the plastic cylinder head cover. How the PCV system works All engines with pistons always have a
Dirty/clogged intake valves - Citroen C5
  We can never stress the importance of cleaning the intake valves frequently on THP engines. Even more so, when the car is to be remapped. The engine has to be completely healthy to produce more power, or the problems will come back to hunt you and cause big failures. While the owner had suspected

This Citroen C4 comes equipped with the 1.6 e-HDI 115hp engine and EGS6 gearbox. It is definitely one of the nicer new cars to drive.  Creating a remap for it meant that the gearbox needs to be kept in good shape. The automatic gearboxes from Citroen/Peugeot do not like the extra torque at mid rpm
