Hi, I have a 2008 1.6 DDIS SX4 with 41,000 miles. I need to increase the power output of the engine. Can these Diesels be re-mapped and if so where can I go near Preston Lancs? Are there any other DIY simple mods that can be done ie rear disc conversion, ride height, bigger discs at the front. Is a great car and would prefer to modify rather than get another car. Many thanks Kevin
