Re-tune after 3,000 'verter?

By april I'd like to get a 3000 stall converter (hopefully yank or PI) along with a transgo hd-2 and a 30,000 tranny cooler. I don't understand stalls that much, but I'm guessing I need a retune right? I'd like a little info on them I'd appreciate it. Thanks!

you dont really need it but i like to a little just to adjust the part throttle shifts....to me its more of a comfort thing, i dont like having a cam and a stall and the chugging feeling when the rpms drop to low

yes
