Lockup box

I run Ben's (bt diesel works) box on mine and have a good results. Street or strip it's great. I just leave it in auto for the most part.
I've had Ben's box on my truck for roughly 5 years, it can't be beat. The auto function is a lifesaver. The DHD one works as designed but heaven forbid you forget to flip it back off, that's a hassle I didn't want so Ben's box was perfect for me.
I bought it used and had him update it, turn around time was 2 weeks between me sending mine in and him sending it back. Talked to him on the phone, he is a really busy guy so patients is key.
There are 2 codes that come up after installed but it's because of how you wire the box in, they are ghost codes basically they do not affect anything whatsoever.

What I run also, works great! You know the converter is locking up as supposed to unlike the BT that has some safe modes in it that may prevent you doing exactly what you command it to. But I sled pull so a little different application.
WOT, the shift and TC lock up pattern is the same between either mode.
I run the stock TCM setup with modded lock up tables. works like a charm every time and no extra buttons.
Please correct me if I'm wrong since I've mostly only messed with the 5 speed and haven't messed with the lockup boxes but doesn't line pressure drop any time the TC locks unless the knockdown valve has been modified, ball removed and you have replaced the spring? Isn't that the only way to eliminate pressure drop. unless we are talking about the LML where, I believe, the TCM has partial control of line pressure?

Couldn't you swap the tables in the TCM with EFILive to start up in T/H and have the same effect with a built trans?
