Hello driving since 03/2009 an i30 1.6CRDI with 116hp have now about 20tkm down and think since my first motorway ride to a chip for the engine, because the starting from 160km/h starts to swallow much more and is at approx. 200km/h close. I am actually one of the average driving on the highway about 160km/h and think with a performance increase then the less consumption. My question has someone already an increase in performance, if yes how much horsepower and what experiences with it.
