If you mean a "Performance page" that manufacturers like Dodge put into the infotainment to see current stats like boost, horsepower etc that kind of info usually exists because they don't give it to you in the Cluster.
The Blackwings allows you to add actual usable info to your cluster that you can see whenever you want so there really isn't a point of adding a "Performance page" to the infotainment that would only serve to duplicate this.
Its also marketing, Dodge does it because their thing is to showcase ridiculous cool things that are in reality useless. Its cool to see that pointless info on a page on the screen when the car is designed to just do burnouts and make noise but you will almost never go to that page when you drive the car but it seems cool when reading about the car.
The Blackwings have a focus on performance and not focusing on showing off weird metrics that don't matter, GM itself has this mentality with their performance cars.
I like Hellcats as much as the next guy and I can understand having a performance page in that car but for the Blackwing it doesn't make any sense because GM gives you actual usable info and makes it accessible through your gauge cluster, because thats where you want to see it when going hard on track, not looking at a Performance Page in the McDonalds parking lot with 245 width All Season tires.
Different goals but at the same time it is just software so I guess there isn't a reason they couldn't add something like that but I don't think a lot of people would actually use it based on the buyers of Blackwings or prior V cars.
