OK, I've had the wastegate control adjusted, and am now getting "almost" book MP. I climb at 2700RPM, full rich, engaging the turbo at 3500ft ASL to maintain 27 inches MP. My fuel flow is 17 GPH. This is according to the STC manual. Once at altitude, usually 15000 to 19000, I reduce RPM to 2600, pull the mixture back to 10 GPH, close the cowl flaps, and increase the MP back to 27 inches. The numbers on the EGT gauge mean nothing, it's just a relative pointer to show peak EGT, and mine is about 75 deg. LOP at 10 GPH. The engine temps drop from 380 CHT to 300 CHT, and the oil temp drops from 210 to 190. TAS is about 170KTS. These numbers are from my recent cross-Canada trip - 10 provinces in 30 days. I'm happy with my installation now, just wish I had more room!
