I guess it wouldn't hurt to try it anyway but the Hypertech takes an eternity to program. How long does it take to re-program with the Gryphon?

Ok
From my understanding of tuners/programmers is this.
Once the pcm is flashed with a new tune it cannot be removed unless reflashed.
I assume the Hypertech has the same proceedure as the gryphon.
So by removing the battery, the pcm's memory has not been altered due to the pcm's flash memory.
However the Keep Alive Memory resets and sends a p1000 code and the only way to get rid of this is by the drive cycle reset. This takes 50-100 miles.
The gryphon only takes about 5-10 min to program initially for canned tunes with custom options. The canned tunes are kinda similar to the hypertech tunes, they fit a lot of trucks. But when you get one with custom tunes only about 2 minutes.
Custom tunes are for you and your truck only. They don't work on other trucks that are the same as yours.
