No.
mkoesel is correct on this. The best shift point for this car is exactly at the rev limiter. Not one rpm shy of it. Of course, that's not practical, but closer is better, and closest is best.
You're pushed back in your seat at the shift not by power or torque, but by rotational inertia. The engine is forced to slow down in an instant by, say, 3000 rpm or more on the one-two shift (less as you go up through the gears), and that energy is transferred through the driveline to the rear tires.
If the auto has a setting that will shift at the rev limiter, that's the one to use. Otherwise, use the one that shifts at red line.
