The reason you saw RPM stuck is because of DSC took action.
At hard acceleration, your wheels start spinning and car is becoming unstable. In order to avoid this, DSC takes action, applies brake and cuts the engine. your car moves forward and then DSC releases the power and disengages the brakes and let car go smoothly.
When you turn the traction on (MDM) you give DSC some freedom to put down more power and torque and that's why you felt wiggling.
when you turn off the DSC completely, then it is the deal between Man and machine and you have to control the car by yourself without any help of ECU. Anyways, I believe M5 can beat ZL1 but you need some experiences. I recommend you to go to BMW Performance driving school if you are interested in having some skills. Don't follow people experiences since this car is so powerful and you can easily lose the control.
Goodluck
