Well the car does need a 160 degree thermostat. He tuned it with that in mind, as I told him i'd have on in in a week (Got one for $32 shipped from jegs.com). The stock thermo definitely makes the car run too hot. We had to wait awhile for the car to cool down. I'm sure it'll probably be putting down over 351whp in a cooler environment, and with the new thermostat.
