I had a hard time finding info about this because the STS blog that contains info about it is under construction now. Luckily, Google has a cached copy of it.

The oil-less turbo being marketed as "less maintenance" and "no dealing with oil" seems funny to me. You have to manually re-grease the bearing occasionally. With Prodigy's oiled turbo, it uses your engine oil via an already available pressurized oil port on the engine. Just change your engine oil as usual. Where is this "dealing with oil" that you avoid with an oil-less turbo?
The "cooler intake temps" claim is also funny. The stock air box is used, so it does not draw in any cooler air. The long air intake piping runs near the engine and near exhaust pipes in some places. The air is then compressed (heat added) by the turbo, and there is no intercooler to cool it down. What is their baseline comparison they use to claim that you'll get "cooler" intake temps? I think they just copied/pasted from marketing for their other systems that have a basic cone filter intake near the turbo under the vehicle, because on those systems, they really are cold air intakes.
The fact that the "tuning package" is an upgrade option (Diablosport tuner, MAP sensor, injectors) kinda worries me. Sounds like it might not come out-of-the-box tuned and ready to drive. That will require some confirmation with STS.
Then there's the general layout of the system. Location of the turbo where it can easily be dunked in water, snagged by things, dragged through mud. And the miles of intake piping. That can't be good for turbo lag.
The best feature I see about this system is that the stock catalytic converters are retained.
Only one way to find out how it really compares. I think JeepLab needs to expand their shootout comparison to include the STS turbo
