Any thoughts on "why" it locked while attempting to flash it back to the tuned file? Just basically looking to "add" to the collective knowledge here on do's and don'ts .. NOT on a witch hunt here..

PS.. do you guys have a "money back" guarantee on the tune? I had contacted you guys a while back on my Roadster (3rd car between my wife and I).. I've tuned the other 2 .. #3 without a 74mm throttle body (upgraded on others) runs out as good as them (2HP under per Torque Pro). I had hooked my computer up to it and sent you the ecu file.. and was told in brief.. it wasn't tuned. Does that file actually contain enough information to accurately determine this (no parameters vary from OEM) .. or just basic information such as Vin..? I just don't want to drop $300 to find it runs the same because "XXX" companies tune was done in the past with an untraceable history.
