You can't get a stepper to go that fast, even with no load. You'll need a different type of motor.
You can do full steps with that driver, but at 2000 rpm you need 400k steps per second. I don't think the driver can keep up with that pulse rate.
If you need precision and speed like that you need to look at servo motors and drivers.
