I noticed your thread here and decided to see what was up.
I replaced all of the canned tunes with custom, so I cannot compare the custom to canned any longer. And, I stopped running the canned tow tune a few weeks before I received my custom tunes due to transmission shudder. But, I do remember feeling that the canned tow tune would significantly out perform my custom 87 performance, although the shifting of the custom tunes blows the canned and stock tunes out of the water.
I was curious if we had the same HEX as I've read about some problems mine has caused with custom tunes. I'll step out of the way and let you get yours figured out.

Ok i had decided i expected too much but i think i have the same setup you do (07 5.4 373LS 4x4 and same hex, although i have an s&B CAI) and im sort of in the same boat. I say sort of because i have noticed gains but the differences from 87 tow(edge) to 87 performance(custom) were not what i was expecting, particularly b/c i got no more fuel economy. maybe this is related to our hex code? Dont get me wrong, im happy with my gryphon i just feel like from others responses i missed something
