This is from my IO-360 RV-8 a couple days ago. 171 KTAS, 6.3 GPH, .1 GPH spread between cylinders. Note all cylinders running between 23 and 26 degrees LOP. 52% power calculated by the Dynon D180. This was stabilized flight with the autopilot engaged. I also have no issues with takeoff power...I had Don help me and have two of the cylinders slightly restricted.
