The stock tunes include:

1. Transmission only - firms up your shifts
2. Towing - this one gives you much better performance when towing loads that are 2500# +
3. 91+ Octane Performance - this optimizes your truck for high octane gas

The tunes also eliminate the throttle lag that seems to plague these trucks and may improve your gas mileage and power. You can also adjust for aftermarket gears and different tire sizes.

But, the reason you want a Gryphon is for custom tunes that Bill can write specifically for YOUR needs.

For instance: I pull a 3600#, low-profile trailer. The canned Tow tune is not really set up for this situation. I have a custom tune that is.

I wanted a tune that helps me get better fuel economy using 87 octane gas when I'm not towing. Again, I have a custom tune that does this.

Do you have mods such as a CAI? If so, you want a custom tune! Do you want to use 93 octane gas? You need a custom tune.

As far as I know, the E10 gas has pretty much become the standard and I think all the tunes account for it. Bill will correct me if I'm wrong.

Hope I've been helpful!
