Tangentially related, anyone else try seeing what the minimum possible fuel flow while staying aloft is for your plane? I needed to build a bunch of hours for insurance reasons while not going anywhere in particular very quickly, so I spent some time playing with this and got it down to about 12.5 GPH total (10500', 6.5 GPH front, 6 GPH rear at about 21" and 2250 RPMs). Couldn't get it much leaner without intermittent missing. 1975 P337G, no GAMI injectors on here. Photos attached showing EDM-960 display and airspeed.
Single engine with the front prop feathered at 10500' (while loitering over a rural airport with a 5000' runway) actually took more GPH to maintain altitude than with both engines running.
