Rocket numbers

Coming home from Cape Cod the other day I recorded the following numbers

OAT 16.6 C
ALTITUDE 8500
MANIFOLD 22.5
RPM 2200
CHT RANGE 351 -378
OIL TEMP 188
FUEL FLOW 11.3 GPH
MIXTURE 75F ROP
IAS 177 KNOTS
TAS 206 KNOTS

I can run LOP peak where mpg go up but speed goes down and time on route goes up. At the end of the day it does not save me that much fuel and I like how the engine runs at these power settings. This works out to 21 mpg which is considerably more then my pickup truck! Grounds speed on the way down of 216 knots and coming home 201. It is a nice way to cover a lot of ground, 500 nm in 2.5 hours.
