I can't see any difference really that all engines are compensates for altitude. Turbine or blown are all compensated can't see why this engine won't be any difference when it and if it get certified.
The test will be seen once it starts to fly. I'm sure there will be bugs it's going to be and if they can fix them.
Any one remember the hype over the thunder engine. It preformed better than the turbine engine in a 690 commander as I recall. Then sold some stc certified now gone and stc removed.
Time will tell.
