Bossman, unless you are running non-OEM tires or gears, program the PCM without trying to customize anything, at least at first. Get to know wht the new tune feels like. And, the Gryphon needs a non-customized tune to properly set up its stock files.
I don't know why you'd get the errors though when you tried to use the Custom Options menu but there are two possibilities:
1. It was cold when you tried to do this. The PCM and the Gryphon's electronics don't like extreme cold or heat.
2. The battery voltage was low. The Gryphon has to do a lot of work when it builds an "options" file and it needs healthy battery voltage. If you have a low Amp (about 2 Amps) trickle charger, it would be good to have it connected to the battery while you do ANY programming of the PCM to insure there's sufficient voltage. Also, make sure your accessories (A/C, radio, lights, etc.) are off.
