On the older V7s at least, the Agostinis do sound good - probably a bit better than the Staintunes, (but not &1200 better). Beetle's latest map for the MIU G3 1TB V7 works really well on my V7 Special (Mistrals with dB killer in). My recommendation is to try out his map for your bike (with the Staintunes) before spending the extra. However, if you find somebody who wants to swap the Agos for your Staintunes, it's another story.
