I got the ECU back from AF1 today. There can be no debate on it whether or not there is a significant power increase. It does for sure. The big difference is in the first three gears. Now it will hit the red line before you can blink.
The reflash may not be for everyone. If I was going to use the ST for the same thing I used my last Wing for, rolling down the highway for miles on end at 80mph doing the long distance thing, then the reflash would be a waste of money.
If you ride mostly on dirt and gravel roads, the reflash may cause as many problems as it fixes. Too much power can be trouble in the wrong place. YMMV
For the kind of riding I like to do now, it will be perfect. I like to get on roads similar to the Dragon down at Deals Gap and play in the curves. I think the reflash will work well busting from curve to curve in the 30 to 70 mph range. I only put ten miles on it today, but I'm sure I'm going to like it. The $450 was a tough nut to crack, but what the hell, if I keep the bike for four years, it works out to about $9 per month. That makes it sound better anyway.
