Ready to order a Gryphon but have a few quick questions...

[bivenspack]

Okay, I'm ready to order a Gryphon. I have an '05 Expedition Eddie Bauer w/ 5.4L/automatic and only the Gott's mod done. On the form do I choose the 2004-2008 F-150 option (there is no option for an Expedition)? Also, if I order a custom tune at the same time will I have to wait on the custom tune or will I receive the Gryphon and then be contacted when my custom tune is ready? How do I get the HEX code? I don't have a tuner at the moment. I want a performance tune that will give me the best gas mileage increase but still be able to tow occasionally. Which custom tune should I order? Any help prior to ordering would be great.
