Since you looking at all you options, take a look at "Land & Sea" dyno. Thats what C&D racing uses to tune all of there bikes. From what I have herd they are quite a bit cheaper since you not paying for the "big name". You can go to there web site and download there interface and play around with it. I knew nothing about there software when I got my bike dynoed by my local shop, then went to there site and downloaded there trial software. Seemed pretty simple to use, I overlayed my dyno graphs with no previous knowlege. Seems pretty user freindly.
