New Converter, Different Shift Points?

Did it ever occur to you the taller tire had the car going faster at the shift point than the short tire. Think about the physics that comes in play when that happens. The difference in the load on the stator, maybe, Aye... No wonder it wont recover. BTY: there are subtle changes that can be done to a converter that has no effect on stall speed that helps with recovery and TQ multiplication. You could even drop the pump pressure and make the converter act entirely different. Why do you think that any serious Comp racer or serious SS racer has at least two or three converters that all stall within a few hundred RPM of each other?
