Re-Flash...Unanswered
We tried too. IT is difficult. Not enough of them out there to be worth trying more, so prolly just live with the piggyback. Does some of what you can do on reflash but not all. But fuel is most of the work you would want to do. Timing is something that would be nice but would affect Emssions. At least fuel curves does not effect emissions. At least when the piggy is removed you are back to stock with reconnecting 1 wire.
