I know you live in FL but on your coldest days with the heater blowing, what temperature does it run? Probably right on your thermostat rating. And now in the summer, the cooling system is no longer...

If you are wondering whether or not it can supply adequate fuel volume for the hp you are making, you check pressure at WOT in the upper rpms.
