Hi! I hope this will help other Bravo owners who struggle to run the TIO-540-AF1B at Peak or LOP TIT.  But first, in full disclosure I am not an A&P and this is not advice. I am simply illustrating my experience with this engine, and it or may not apply to you. Always follow the POH when you are not sure that your deviation from that document is in your best interest. I am a lean of peak fan, always have been. It comes back from my days of working on non-aircraft internal combustio
