Wait, so do you guys lock the converter through shifts?

I was talking to bison and I guess i should go re read what he was telling me, very knowledgeable person.

Anyways, it sounds like some of you guys lock the converter, and keep it locked through shifting?? I always thought you get into third, then you would lock the converter? Do you lock it up right after the launch or what?

Normally half way through second.

I wait for a second or two into 3rd. There prooved to be way too much bog at the 2-3 shift to lock in anytime in second. For avoiding the pitfalls of the huge 2-3 rpm drop bogging things down, you'd need to be making a lot more HP than I was and spinning something close to 6000rpm at the shift point.
I was only running mid 11's so it severely hurt my times and mph locking before the 2-3 shift. Maybe if the TCC clutch isn't 100% efficient it would slip enough to allow this. Unfortunately I'm running a 7 disc. It is very unforgiving at a 100% efficiencey when locked.

I only lock it in 3rd. Trans guy says locked shifts are a good way to break hard parts.
