Please explain. I'm not sure I understand.I agree with MTV, you are leaving a lot of horsepower on the table. You should be able to go to full throttle or nearly so down low without exceeding 2700 rpm. At altitude your maximum manifold pressure will be reduced. So at 15,000 you would be lucky to get 60% power at full throttle 17" mp and 2700 rpm. Take a look at Lycoming's power chart.
At altitude where I fly 90% of the time I can go WOT with the Catto in level flight and it turns 2650-2700.
Overall Ive been pleased with how the Catto does at altitude. It doesn't seem to run out of bite like the Borer reportedly does.
