ok i bought a diablo tuner (VR7140) off of this forum used but unmarried. It was bought with a vortech unit and sold to me b/c he already had a tuner. Anyway i cannot seem to figure out how to download my factory tune. I plug the tuner in push the 'performance tune' button and it says 'STD output' 'Charge-Cooled' ' Air to Air' and 'Original backup'. I click on original backup and the screen that comes up is 'this will restore the original backup and reset the tool'. Click that and that and get no, yes and force. Click yes and get 'cant restore original backup it was allready restored or was never saved.And my last tune writen on the tool was original backup. WHAT DO I DO??? Please help me. i put this on the diablo forum but no one has answered yet. I figured with so many people on here buying used stuff someone has ran into this. Ask away if u need more info... THANKS!!!!
