What happens when you press the tachometer down?

When I press the pedal down about 75%, the tachometer rises quite a bit and suddenly I get a ton of acceleration out of nowhere and the RPMs jump really high,almost like a turbo kicking in. (Shifts at 6k, redline is 6300rpm) It does not feel like it’s shifting.
