904 Valve body decision

I don’t mind shifting all the time. I have to when driving semi so doing it in my car won’t bother me lol so then if a guy doesn’t tie the TV cable fully back but say 3/4 then the shift points get lowered and things aren’t as bad? I know I’m probably asking some dumb questions and I’ve read up on some info about the throttle valve and pressure and etc. Just most of that was on a stock setup and doesn’t quite help answer what I’m trying to do.
