2015 Peugeot 208 GTi (THP 208)

Equipped with an EP6FDTX engine, the 1.6l turbo found in the Peugeot 208 GTi is reported as having 153kw at the engine by the manufacturer, capable of 0-100kmh in 6.8secs. Needing to conform to the very strict Euro6.2 emissions regulations means that this engine not only has to produce good power stock (208hp) but also features a complicated catalytic converter system. It is the most powerful installed on the 207/208 platform and makes the car very nice to drive.


But there is a catch. When the 208 starts its life as a car at the assembly line, the front crashbar and radiator assembly is common for all turbo versions. Ranging from the 1.2T Puretech 110hp and 1.4HDI with 70hp, up to the GTi, they share the same radiator and intercooler. If you happen to be on the bottom side of that power range, the tiny,vertically mounted 2 liter intercooler unit might be enough for you. If you are a GTi, it means that heat builds up easily into the intercooler, specially on dyno where airflow is limited by definition, reducing top end performance.

A pre tune Dyno run saw a best of 114kw @ the wheels. With a custom stage 1 Etuners file calibrated peak power increased to 125kw. Midrange gains of +20wkw, combined with sharper throttle response left the GTi struggling for traction on the street.

Further gains can be made with Stage 2 hardware.
