I always hated how it would struggle going up a small hill just trying to maintain speed. I adjusted my gryphon's TC lock/unlock points as follows:
1 lock: No change
2 lock: No change
3 lock: +5
4 lock: +10
1 unlock: No change
2 unlock: No change
3 unlock: +5
4 unlock: +9
With this set up I can go down the interstate (75 - 80 mph) with moderate hills and it no longer struggles. It just unlocks right away when the accel is touched and you continue perfectly. Night and day from how it would just crap out and bogg to 65mph before 1400rpm finally came around.
I didn't change any shift points or WOT settings, because these weren't my issue. But, for performance it's better to have it shift after your "peak power band" (2500-3500 rpm)...
1 lock: No change
2 lock: No change

4 lock: +10

I started out with what the user has above and went from there. My bog down is virtually gone, but im still having idle issues when running the AC and or Heat.

Tried that too. Helped in the street but made the freeway horrible! You shouldn't have to tune your truck to make it progress through the rpm band lol.
I think that a lot of you guys have a different issue then the original poster and I have, I wish I could take you guys for a ride. You would freak!
Still trying to get to ford, money is a tad tight so it looks like I live with this issue for another 2 weeks.

Change the trans fluid?
I wonder if doing a full transmission oil change (i.e through the trans coolant lines) would fix the situation? I've thought about it for my truck, but dropped the idea thinking it was the VCT solenoid. Now that you mention the TC, wonder if it's that afterall.
