The tune file can be fully read out from the internal data port, it's not something that just Kory figured out. What he did do was figure out a way to set fueling limits inside the ecm via an existing input so as to give different max power levels. And what he did was discussed on the efilive forum a year or 2 before he and ez link came out with it. How it's being done can all be found on the efilive forum, as well as the reason why efilive will not directly support it. I'm not trying to downplay what Kory has done, but your post made it out like he's the only one that can do it which is 100% false as these same basic ECM's had been cracked, read, and modified oversees I believe before he even started doing tuning. Efilive had tune files and made basic software to modify it for others oversees long before they released it for there own software.
As to the tune file, I have it, and offerred to send it to him for free. Most of the tune files for up to early 15's were posted on 4shared about 2 years ago. Several of us downloaded them, and are willing to pass them along for free.
