Has anyone tried the BMS JB4 tune?

Looking into getting one for my 2013 genesis coupe 2.0t, but haven’t seen anyone do it yet? Says compatible with gen coupes, but I haven’t seen it done yet?

I'd get a real tune.
From what I remember (someone correct me if I'm wrong), these types of things just trick the ECU into seeing values from the sensors that are not real, and the power comes from the ECU trying to compensate for everything.

Friend of mine had one (another tuner) on his GTI and it was a total **** show. Eventually, he got an actual tune and the car ran really nice.
