To me this sounds like they have partnered with another company providing the OBD flashing exploit hardware for the MEVD17 ECU. I am taking a shot in the dark and am assuming it is this:

Its discounted to 1900€ until Christmas eve or so and this appears to be the actual technology behind their tunes? This seems like an authorized dealer type of hardware, where you'd go and get your Mission Performance or other tuning company's flashes done. I saw @Alex@abrhouston listed as an official 'distributor' I'll see if he has any info. Either way, that is great news for people with compatible ECUs.
Here is the information on the device:

Notably, the B48 and B58 are excluded from this list. This device appears to be tied to the internet for several security reasons, likely all the exploitation is done on the server side so it cannot be easily reverse engineered, which is smart.
