We were running about 210=B0 F for Oil and 420=B0F for CHT.

I'm not entirely familiar with the TIO-360 but those CHTs sound high to
me. Maybe I'm just conditioned to seeing temps around 370-380 in the
Aztec/Lance (non-turbo) but John Deakin's excellent articles on this
subject warn of exceeding 400F. Like another poster suggested maybe the
FI system is out of whack?


They are Continental engines rated for 200hp at sea level and 215hp at 1=
2,000ft

Turbo engines with a higher power rating at altitude? Never heard of
that, but then again I only have a few hours in the PA34-200T.
