Specifically for those folks here with a TSIO-360-FB engine (TAIII) with the Black Merlyn waste gate controller, what are you seeing at startup for manifold pressure and at what RPM? My airplane has the above engine (and an intercooler but I don't think that's relevant) and I typically see 17" MP at 1000 RPM. This seems high to me and am looking for more data points. Induction system was checked for leaks but nothing significant found.
