I just don't see how it could be done economically even as a DIY project.
The SC guys have two solutions. URD uses a stand alone computer. They didn't crack the ECU code. Magnusson already had the encryption keys. They built all the prior TRD SC models, so they're the only ones with the "keys to the kingdom". No one else can really compete very well for that reason. The big benefit I see with Mag SC is that it's as close as you can get to an OEM option. And there's a lot of value in their expertise.
I think you could probably use the URD computer to work with a turbo system, but I don't know how much work it would take in the tune to actually have a daily driver quality product for a turbo system. I'm really curious to learn more about the 3.5L twin turbo that supposedly will be in the next gen tundra/LC300 and whether it's some iteration of the GR where there might be options for parts interchangeability - like turbo fitment to the 1GR and things of that nature. My guess is that it's a completely non-compatible engine. But who knows.

Does Magnusson have the keys for the 5th gen though? From what I hear in the SC thread their tunes are sub par, so I'd be surprised if they had full access. Not many reported issues with the URD unit, which I would lean towards when I'm ready to blow my engine. Not to mention the substantially more efficient design of twin-screw vs centrifugal in this application.
