@laurreth A further reply from the developer on this for you...
"I'm sorry, I shouldn't have written that post from memory. I checked on the engine performance in the simulator today and the maximum attainable torque at FL300 at ISA is 105%. The maximum performance cruise table that I've been using from the POH indicates that this is the torque available at that pressure altitude with the power lever fully forward. I hope that helps dissuade any fears of undesired performance changes."
Hope that helps.
