Maybe it was fueled up with regular unleaded?

That's BS. Totally. Being an engineer, there is no "one time" write flash memory module. If the factory was able to write in the original code, and then the dealership was able to flash newer code over it, there is always a way to flash it back (like PC BIOS). Otherwise, what would happen if it glitched in the middle of writing the new code???!! "Sorry, we only partially flashed it and can't go back to the original code" That's just stupid.
There IS a way and the techs just either:
a) don't know how to do it
b) fell asleep in the training class on how to do it
c) too lazy to do it
d) don't have a backup copy of your original ECU code
I bet THESE guys will tell you the same thing

It's just as fast off the line, the only difference is you need to press the gas pedal a little further. i.e. on the old ECU give the pedal 20% and you got 20% of
the throttle. now if you give the pedal 20% you probably get 15% throttle. as you approach the higher 50% range, I think it's all the same.
