The FMIC wont be blocking your airflow that much, at most it will be allowing warm(ish) air onto your radiator (the purpose of an air to air intercooler is heat exchenge via airflow), your ECT temps sound fine, and Im sure the water passing through the 800º turbo is going to be affecting your coolant temps more than the IC.
Depending on the age of your coolant you can flush the system and put a good quality long life coolant in there, this should help knock it down a few degrees if it bothers you that much.
Nearly all men can stand adversity. But if you want to test a man's character - give him power.
