I've been running around for a season with a FMF programmer and mostly stock bike which seemed pretty nice. Got my Yoshi pipe on and did away with the AIS system and the EXUP system and did a quick ride the other night and wasn't too impressed with much till I got to the top end of the power flow and it seemed to make a big difference in WOW factor at that point. Got dumped on with ten inches of snow yesterday and some cold "arctic vortec" crap on the way so I'll be waiting a week or so to give it a good test after the "global warming" thaw. Got the feva to ride and I have juiced my bike up to the max less a big bore kit. I'll give an update on the results once the weather allows.
