engine tuning

[hairyuk]

anyone else on here think it would be a good idea to have a sticky on tuning different engines. i've got an aaz and have been looking around the web about tuning it. there seems to be a lot of different ways to squeeze a bit more power out of these engines, i.e. turning up the fueling, increasing the boost on the turbo, fitting different injectors, inter/charge cooling, lightening flywheel, etc etc. what i'd like to see is a sticky with tried and tested methods of increasing power including pictures, diagrams, photo's and step by step instructions. Anyone with any knowledge of tuning there particular engine could put there results on here and hopefully we could have a comprehensive list of engines and modifications. cheers.
