WHEW!!! This thing is driven me nuts! How hot is TOO HOT? See my list of mods below. I'm getting 235-240 while normal driving. It creeps up when the AC is on. Of course, it goes down when the Heat is turned on full blast. But, that pretty much sucks this time of year! Temps were recorded with a ScanTool. Would the temp drop under normal driving if I get the ECU reprogrammed? I STILL haven't gotten that done. I DO have a 160 'stat in the car though.
