I'm sure John would never refer to them as "miracle mods" but they're enough a stride forward that I'm sending my Bidat in for the upgrade even though it was done in November of 09. As I understand it, the power upgrade discovery occured around January of 2010. There may have been other minor modifications during the year since your mods were done and I have no idea what they are. My bistream was completed in March of this year.
