It must be a lot of fun. I envy you, I've never done anything like thisLately, when I'm not playing computer games, I spend most of my time in my garage. At the moment I'm trying to rebuild my old car. I want to make it perfect and fast. And at the moment I'm trying to do some real chip tuning. It is very difficult to do it yourself, roughly speaking, at home. You need the right amount of tools to diagnose the car. I have ordered a set of such tools from www.ecutools.eu, so hopefully I will be able to finish the chip tuning and move on to the bodywork in the near future.
