The canned tunes that come on the gryphon when you get it are wrtten to cover a very wide range of these HEX codes basically a lot of trucks.
By far they are better than your stock calibration and some people just choose to use them.
They are:
1. Tranny only.
2. 87-89oct tow
3. 91-93oct performance.

The custom tunes are the best. Bill writes the tunes for you and your truck.
1. How you drive.
2. What you do with the truck.
3. How you use the truck.
4. How do you want the truck to perform.

There are these choices he will write for you:
87-89oct performance.
91-93oct performance.
87-89oct tow performance.
91-93oct tow performance.
And so on.

If you have the 5.4 3V you might expect some gains like these:
Up to 25hp running a 87-89 performance custom tune.
Up to 35hp running a 91- 93 performance tune. Of course these gains all will vary depending on your truck.
So there's some more info for you.
