Gryphon on a 7.3L

[renyren]

I will only put about 5000 miles a year on the truck and just want to get better MPG and more power for towing my 6000 lb camping trailer. I need gauges so that is why I am interested in the gryphon. I don't know how much people need to switch settings. most people say to get a chip but for the reason of being able to shift on the fly. If you can put the same tunes on the gryphon then if I want to change tunes down the road if I get a bigger trailer I can buy it and download it from your site right?

All I can say is WOW!! I have fuel sipper, extreme and max tow. Holy cow Extreme smokes the tires and max tow is unbelievable. I havent figured out MPG on fuel sipper. But, I am very, very happy. Programming doesnt take that long and its usually for the whole day. So I dont mind waiting 3-4 minutes to change. I cant recommend it enough and the gage monitoring is an added bonus. I love it!!!

i just built a truck specifically for towing, 2002 f-550. i went the gryphon because i did not think shift on the fly was necessary. i went with 20 tow 40 tow and 60 econ. i expect to put it in 40 tow and leave it there indefinetely. i tow a 40 foot toyhauler weighing 18,000#. i have another truck that is heavily modded, i went with a shift on the fly for that truck(over-rated.) the gryphon is the hot ticket in my opinion. great tunes, built in gauges. i personally got the pillar mount rather than the dash mount. i could not be happier. i honestly wish i discovered PHP for my first build. i suppose it is not too late.
