Funny thing is when I shut it off and let it sit, it'll go down to about 175 in about 5 minutes. Still going up to 220-225 on the hiils.

140 on the bottom pipe sounds high to me unless it is pretty hot outside. Not sure what it typically is. Maybe others can chime in with what they usually see.

Engine fan kick in at somewhere around 205 - 215?

What is your boost getting up to and pyro?
