I am a professional pilot with 50+ years of experience but, have never operated LOP. Have read all of Tornado Alleys information but still not completely sure about operation. I plan to operate WOT @ 2500 rpm. I always understood that you should operate engine at 75% or less power. According to TAT the fuel flow would have to be 15.1 gph to get 225 hp, or 75%. What if your EGT/TIT peaks, then lean further to get 60 degrees below peak, and this FF is above 15.1? What am I missing?
