No I haven't and I wouldn't recommend it either... a lot of my changes are based on calculations and information I have found browsing the internet but if you open the excel spreadsheet in the last zip file I uploaded it should explain a bit :)
I am (slowly) working on a revised tune that takes SOI (start of injection) into consideration.
'Ecuedit' has said many times that everything has to be considered together, and as I found out you can't make a tune just by modifying a couple of the maps :(
'Relic' also has a few good posts/threads even though he is tuning a Honda some of the information he is posting looks interesting, especially about turbo maps

If you can get your head around that your a better man than me ;)
