I'm in the 7400's and I had the reflash done about a month ago. Yes, my si still can buck like crazy in first at the lower rpms and still have rough shifts from time to time... but compared to the pre-reflash it feels a lot better.
I could def see why you're feeling like you still need a reflash, but I think it's something we just may have to deal with for the time being with the car being a dbw system and all
