Big thanks to Rick for remapping my car . He is not only capable of getting big numbers from petrol cars he can get the most out of diesels too. Very knowledgeable, tells you everything thats going on and does a great job. http://www.audi-sport.net/vb/audi-s4-a4-a4-cab-b8-chassis/204785-karls-3-0-tdi-build-thread.html If I fit a Hybrid/ bigger turbo I know where I will be going .
