When i was running with a DNA stage 1+2 + pc3 +CCC exhausts set up i used the simon kettle map i left the ais tube open and the lambda sensor connected and this made a huge difference to the way the bike ran (map available to subscribers free of charge) so well worth joining
mine is also a 2008 model
