Heading west, I usually wish that 252BH had more power to better buck the headwinds.
But coming back east, it's easy: fly as high as I can, up to FL210. Above that, I start to worry about O2 glitches popping up - they have a way of doing that.
Recent trip back to Missouri from Flagstaff AZ, after a stop in Holbrook (P14) for cheap gas. I saw 330 MPH on the 796 for a few minutes, level. 70% power, and all CHTs below 380. Fuel burn, 14.5 GPH. TAS was 194-199 KTS. Of course, even with the tailwinds, I was still wishing for more power.
