If you upload ( to your pc) the tune in the bike before installing a new tune you should be able to reinstall it before the dealer touched it.
Unless something has changed the dealer is not tracking how many times the ecu has been flashed or even if the can see that number.
Get a cable, save time and frustration do it your self.
tiger dude, don't remember is your bike is new, if it is and the drive is not to far the dealer. They should get the bike running correctly.
It's a good engine, don't give up on the bike. The dealer maybe.
