So I only used boost for takeoff and for normalization most of the tim= e=2E I liked operating  28- 30=E2=80=9D with the prop between 1700-200= 0 rpm=2E Rich or lean to keep the EGT under 1600F and intake temps under 14= 0F=2E

What boost are yo= u running?

And I meant to ask, my friend is asking what power sett= ing we consider the engine to be OK with for continual operation?
