Circling back around to close this off, I ended up sending my ecu to vcyclenut for flashing. He was great to deal with, answering every stupid question I threw at him quickly and professionally. The turn around time was less than two weeks even with the postal delays.
Today was my first ride of the season with the flash. Only put about 150km on but WOW...what a difference. Pulls smooth and hard in every gear now...no more hesitation, popping, shuddering on decel or snatchiness, response is nice and linear now. I swear it feels significantly faster but that might just be the better throttle response and my needing to get used to it after hibernation.
Either way, I am extremely satisfied with the results. Well worth the money IMO. Worthwhile if you just want better than oem power delivery and don't want to spend the money for tuner and dyno time.
