I will have to lean it out and check to respond to your question but I think it has more to do with the butterfly valve setting. I can check fuel flow at wot and 65% power but that will pry mean climbing to 12500 da or so?
I think I'm realizing some significant ram air horsepower or some significant horsepower increase from the ASA vacuum valve because whereas I only get 2150 rpm static at 1500 msl, I can still wind it up to 2750 at 10,000 DA.
