Citroen DS3 1.6T stage 1 98RON

This Citroen DS3 came to us for a stage 1 ecu remap. The gains were amazing for its small turbo and the customer left with a smile on his face! The expected gains are quite high: +35hp  (50hp max at the midrange), +60Nm of torque just with the ecu remap and everything else left stock.
The Peugeot 207 Rallye THP 1.6 Turbo comes with 150hp or 156hp as stock. Remapping its ECU brings very good results both in power and torque. Engine code is EP6 DT. Upgrade specifications for the Stage 1 ECU remap -Upgraded intake kit -Upgraded catback exhaust -98RON fuel Performance results Maximum horsepower: 195hp (measured 152hp as
