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.
Yes and no; the further back that you tie that Throttle-Pressure lever, the harsher the Part-Throttle up-shifts will be; and the later, and the automatic downshifts can get pretty aggressive,to the point of skidding the rear tires.
But if you do not tie it All the way back, then at Full-throttle, you run the risk of frying the clutches/bands.
