Is it possible that the ignition key was in the OFF position when you plugged the Gryphon back in to your truck? If so, the unit could not "boot" properly.
The solution is simple if this is the case. With the key ON (engine not running), disconnect the OBDII cable from below the dash, and then reconnect. If the PCM's calibration (HEX) code displays, the problem should be resolved and you should be able to load your revised tunes. If not, let us know.
