Hey there steinrk, and welcome to this forum. I do not believe we have come across this form of tuning box on our forum. I myself have a tuning box from Germany, and as you are probably aware there are many of them out there in the market. The remote control is an interesting idea, but I would not consider having that option for the simple reason that the box would still be visible in the engine bay if it was to be inspected. I have a feeling the remote control option is not the solution for you unless you have other people you do not trust who drive your car. In my situation it takes me about 2 minutes to remove the box from car if I have my car serviced by a Hyundai technician, and there is no evidence of having used one by their diagnostic equipment.
From my personal experience there is nothing wrong with using a tuning box when the car is still new. Just remember to take the box out when servicing.
Nice car by the way and a good choice of colour too.
