My preference for TSIO-550 engines in the IV-P's is to climb at WOT x 2600 or 2700 RPM, with sufficient fuel flow to keep the TITs down to no more than 1350F, or less. With the baffling properly re-designed, that will keep the hottest CHT down to under 380F in the climb at 145 KIAS in the climb. Operating it that way, the ROC is rather spectacular. S.L. to 20,000 in 10 minutes or so. Regards, George " coming close to 220 hrs in my IV-P with routine LOP as per the GAMI people but without gamijectors since the engine is quite efficient with a reasonable spread between CHT the hottest cylinder being #2. Usually cruise at 21K to 24K going east and 18K going west, I climb full rich and 2500 rpm the limiting factor being 400 degrees CHT which I try not to exceed by "
