There are many helpful tables in there. One of my favorites is under "Pressure control" named "Off TCC". This table will add line pressure to help hold under large loads or smaller aftermarket torque converter clutches.

Now for your question. The main TCC lock-up table is found under;
"Trans"
"Auto TCC"
"Apply/Release Speed"

Thanks Wilde- I've seen the pressure settings but I understand that you can fry the torque motor in the tranny if ya dial it up too much which can be averted by getting under there and installing a shift kit. I'm all for locking up a little sonner, though................

3 weeks ago, it ran a 12.65 @ 105mph with converter unlocked.

last night it ran a 12.57 @ 106mph with converter locked.

last night it was in the mid-upper 70's & 90%humidity.

3weeks ago, it was mid 60's, and like 50-60%humidity...

I'll be waiting for some cold weather now to do some real comparison..

Charlie has mine locking at 90mph, my RPM drops noticeably when it happens but the SOTP feels like it pulls harder...weird.

Makes sense considering if you dyno with a locked verter you put down more power. Even though you drop rpms you won't lose 25+hp through the stall slipping.

I'm trying to guess at what my truck is gonna run judging by a 0-81 blast on hptuners. 81mph was my old 1/8mile speed and did it at 8.7 i think it was.
Trying to do a little math on her and try to guess at it.
8.7 was the old time. Not the new one.
