Hey all - decent looking forum with a wealth of knowledge to tap into by the looks of things. I am the proud owner of a 2003 Z4 2.5 in Titan Silver. I wasn't looking for a Z4, having started my foray into the world of cabs by buying a 2001 Porsche Boxster S last Sun. On monday it had blown up with £13K of engine damage and by Tuesday was on a low-loader heading back to the bloke I bought it from. So, I had a look around and decided that he replacement would be a Z4. In fiarness, I am over the moon with her. Not as brutish as the Boxster but it actually feels as if it is built better and instantly 'feels' like BMW reliability and quality. I am interested in finding out what can be done to tweak her slightly in order to gain a slight increase in performance etc - maybe a remap to start with. Anyone any pointers? Anyway, hope I can help contribute in some way.
