HELP!!

[zippman1]

Hi I have recently purchased a gryphon cs. I installed and i love the performance except that it shifts extremely hard. Like someone is kicking my back seat as someone else has said. I have dialed down the shift firmness to -4 for all three shifts but it is still too hard! Tow tune and 91 performance tune. I like the power but the shifting sucks. Even my gf asked what was wrong when i was driving. WOT it really kicks and normal driving a lot lower kick. I would like firm but not like riding a bucking bronco.
Also how do i get my hex and all of the things i need to start the process to getting custom tunes?
Please help! I have a 2008 f150 5.4 flex
Also i have a volant cai and about to install banks catback sido. With the cai the check engine light has not come on.
