Gryphon on a 7.3L

The tuning for the Gryphon will be the same as that for the Phoenix (including FU and FU2) chips and we can even compensate for the unruly and undesirable calibrations for the most part.

What is boils down to is what makes the most sense for you. Yeah, the Gryphon doesn't have an analog needle to catch your eye, but it does offer visual and audible alerts (flashing display and warning beep) when certain parameters reach a predefined (by you) setting.

The folks that do run the programmer are usually quite happy with it as it fits a specific set of needs quite well. For those who prefer to be able to switch and play, the chip is a more desirable way to go.

I hope this helps.

I have read this whole thread and left with some unclarities.

- Can both the chip and the gryphon adjust speedo for wheel size changes?
- What about the stock computer code does the chip bypass and the gryphon does not?
- will one see better MPG with the chip codes over the gryphon?
- Both options appear to do shift points, is one easier on the tranny?
- I have a 99 F250 7.3 - does the gryphon have an egt probe to read temp, or would I still need a an egt gauge?

Here are my goals:

- Driveability for highway and travel with the maximum MPG possible. Not looking for the most HP, smoke, etc.
- Light towing
- occasional 'fun' factor
- eventually will go to veggie conversion with a dual tank system
- reliability - could be taking this rig south of the border to costa rica

Truck has 141,000 on it, brand new to me. 4inch exhaust, stock injectors, k&n filter (will replace with new intake - not sure on DIY or manufactured one), 4inch lift, larger tires (spacing onthe size and it is -8 outside right now)

I am only really interested in mods that really help MPG for long distance traveling, of course some performance gains will be great.

Thanks
