In heavy trucks like mine and others I've done here's what normally I do.
Almost half on the shift times, .3000 is where I go depending on fluid temp in the table.
Add 5-15% on shift pressures for gears 1-4.
Add 10-20% to on-coming pressure presets.
Sometimes do .9000 on the shift torque factor and leave everything else stock. I don't touch tip-in limits, torque reductions, limit tqmngt or flare TM.
Had great success with several trucks and friends I've helped, none are pushing tons of power though but hey they work and shift awesome now. My changes are pretty similar to what DDTech's are, though just in a slightly different application.
