Factory top speed settings 2020 HD

[GMC AT4]

Does anyone know what the factory top speed settings are for the 2020 HDs? I have not been able to find this info on the web. For my 2013 HD I purchased a Hyperteck programmer and was able to raise it. My 2001 1500 was set at 85 miles per hour which is the speed limit in some states. Thanks,

98mph as i hit it last weekend driving

It is set based on the tires installed at the factory according to a recent thread....

I believe the tires are q rated which is 99 mph speed rating.  The top speed is set at 1 mph below.

You can for sure feel the limiter hit very firmly at 98mph on my 2020 Duramax.
