These plug in units were popular on the older TDIs as they merely adjusted fuel quantity to suit throttle position (on a Diesel more fuel = more power up to a point as they run at full air flow all the time) and thus were quite simple but effective to use. Modern Diesels obviously have all of the exhaust emissions stuff strangling the system which you don't want to clog up so you have to be much more careful.
But petrol tuning is somewhat more complex requiring ignition maps as well as fuel maps. I notice on the photo of the box there are plenty of connectors on it so it basically looks like a stand alone ECU processor and thus could well be quite advanced, and if the map is written properly should be pretty effective. Looks interesting for sure.
