Maybe the engine driven fuel pump is failing. = We are running low boost continuously in case the engine pump fails and to= address fuel pressure issues at altitude, hot fuel, vapor lock and other p= roblems.  

I understand the engine will not make full power on low boost (re= duce manifold pressure and settle for less power?)   

= Or, it might quit if high boost is on and the mixture is not adjusted. = ;

Dr. Lyle Koen did our last two= physicals.  He was a very likeable guy who built one of the early IV= =E2=80=99s and had over 1000 hours on it.  We talked to him about join= ing LOBO and coming to the Branson Fly-In. 

Given the more knowledgeabl= e than usual witness account, could training have changed this outcome?
