 Art,
 I also have a TSIO-550E from Monty.
 I am far from the expert but of course make sure you have at the minimum FF
at full power take-off OR that your TIT's do not exceed 1300 at Full power
t/o.
 I have engine driven a/c so I do not have the 3rd inter-cooler.'
 I have never had a cooling issue.
 feel free to email me direct if you have any other questions.
