Computer Lock Failed (Dianlo Predator)
Just got my Diablo Predator, tried to install one of the tunes. Gets all the way through the install and I get a Computer Unlock Failed error message.
2002 F250 7.3 (CA), auto trans, 4X4.
Any Ideas about why this is and how to get around it?

exact same problem happened to me. turns out, when i bought my truck used 2 months ago, it had a chip already in it. Take the chip out and reinstall the factory tune. You should then be good to go. Chip is on the PCM above the clutch pedal. Remove it with a 10mm wrench (inside the engine compartment for the plug) and then pull the PCM out from above the clutch.
