Those types of gauges are great for supplemental information, but as main gauge, they have a few drawbacks that, IMO, make them unsatisfactory for street use. First, they tend not to have an odometer. Most everyone wants an odo to measure overall car use, and in some states it is required. Second, they tend not to have the kinds of warning or signal lights that a street car needs, like turn signals, high beam lamps, OBD2 warning light, etc. And third, they tend to be very engine-centric, meaning that signals that don't come from the engine, or aren't in the OBD2 data stream or recognized from their own sensors, just can't be displayed. For example, you will likely want a fuel level gauge on your car- but many such tools (I don't know about TunerStudio) don't have a way to read fuel level in a tank unless it is a recognized PID in the OBD2 data stream.
There are such gauges, but they tend to be extremely expensive (I'm thinking of the Motec series here), which takes them out of the $50 tablet and free software approach, right into tens of thousands of dollars for a full Motec harness, display and accessories like sensors that is installed and setup by a pro shop.
The stock gauge is actually pretty good; it's only real drawback is the lack of an oil pressure gauge. However, with the correct switch, it's easy to wire up the included oil pressure warning light to come on when pressure is low. I've done so on my car, and it reassuring to see the light come on when ignition is on with the engine off, and see it go off when the engine is started and oil pressure exceeds the switch setting.
