The best way I found was to write notes. There's only so much you can learn by reading a screen. I have an A4 notepad filled with notes about how to tune. Comments from DD, Nyet, Snow Trooper, littco, nokiafix etc all to help me understand what's actually going on.
Then more notes from the Wiki, which is also really helpful (a lot more padded out since I became a member). I'm gonna get my boost leak fixed this weekend and get cracking again too. My fuelling isn't too good and there's room for a lot of improvement, epesh a 3 bar hack.
Did you try my file?
