Gryphon on a 7.3L

[muns53]

Renyren,

Disclaimer: I don't know anything about the code issue that Cleatus mentioned.

But, to offer you a different opinion, I bought the Gryphon over the Phoenix for three main reasons: I didn't want to buy and install separate guages, it has the ability to read and clear engine fault codes and it comes with a pyrometer. (Plus, I like a lot of the other "extra" features in the programmer.)

I monitor these 4 parameters on the Gryphon constantly: Tranny temp, Engine oil temp, Turbo Boost and Exhaust Gas Temp (pyro).

I'm very happy with the 65Tow tune for heavy-duty towing and the 80HP tune for everything else. I don't find it onerous to sit in the driveway for two minutes to reprogram if I want to go out on a towing mission that requires the 65Tow.

FWIW, the intake/exhaust mods are easy to do and well worth the trouble. I did the "Tymar/Zoodad" intake myself and had a local mechanic friend put in a 4" turbo-back exhaust from Diamond Eye. I never see high EGTs.

Good luck with your decision!
