I tried a mishimoto thermo in my mild mod'd Evo IX and it ran like crap. It would open up too soon and the car would stay in open loop keeping the temp way down and causing bad gas mileage (dropped from 18mpg to 12mpg). On the freeway, the car would warm up better, but once off the gas and cruizing, the temps would drop a lot.

I know it is not a 370, but should be the same principal.
