I was very unhappy with the original reflash despite my big check.  Downright dangerous.  Put on a pedal commander.  Helped a lot.  Got a notice about a "solution".  When in and had it done.  I was very impressed with the difference in performance and fuel economy.  Don't think I'll be putting the pedal commander back on.  I wouldn't hesitate in taking them up on the offer to reflash the solution .
