Question, So my IO 360 A1A angle valve and Hartzell CS prop came out of a Mooney, in the logs I see the governor being removed and worked on, so I am assuming they had it set up for a max 2700 RPM. So now it has a full dual EFII setup, when I do a practice launch, ( 3 seconds full power down runway, < 40 Knots ) I see 2850 RPM. I have searched and read where folks dial in the fine pitch stop on the prop 1.5 to 2 turns in, to have the prop slightly more course pitch. Is this what I need to do to bring the RPM down? I am trying to understand the science behind this, Also I am doing this at 4720 MSL, does density altitude-altitude play a part in this max RPM issue? Thanks,
