I went back through the TBSS with the cam in it, mostly trying to get 4th gear to work (which I did get working, thank you) and you know...I tried all the stuff you guys wrote here and it really didn't make a difference. I kind of used a combination of the different things 5LE did and I tried the overspeed settings LAZ used, not really making anything better (actually it went back to being worse). I ended up with a good compromise that gave a little smoother idle and better recovery, but I can't get it to idle under 850-900 RPM still.
Oh well...a cam just can't be hidden but so much.
