TTVA by small increments. And some of the parameters such as full throttle shift, kickdown, etc.

As FUBAR said...TTVA and kickdown, full throttle etc.

Most of the rest seem to be valvebody dependant. Try to change something and test to see if it works as desired.

Small change..test...small change...test...circle of life.

I made some small changes to the TTVA degrees table and it completely changed the way the truck accelerates. I noticed less smoke off the line during normal stop-and-go situations too. I will continue to tweak it and see if I can get back out to the track soon.

I was having problems with the flare shifting 3rd and gear hunting 1-2-1. tried few different things trying to fix it, only one tp really help was i rasied my normal gov pressure up 10% , also it spreaded out shift points.

The shift from 3rd to4th always seems to hold on when driving in town, light throttle. If I get off the skinny peddle just a bit it will shift or get on it a little more but if I stay constant it just seems to hold for 3-4 sec and then shifts. Any ideas

Sorry, I should have also added I have tried increasing govern pressure by 5% across the board, Kickdown and I adjusted TTVA in the 5% range from 3 to 5. Now one thing I was thinking is maybe there is too much govern pressure in that area?
