My factory fan switch use to come on at 220 and the temp never went past that. Then the factory switch went out and put another one in and now it goes up to 237 or something like that before it kicks on. Does anyone make a switch that kicks on at 220 and off at 200? let me know!

 

Yes, check out Jegs or Summit - they've got Jet and Hypertech fan switches that come on about 200, off at 185 and another one that's a lower temp than that - can't think of the specs right now, but they run about $45 or so. I know you asked about a higher temp, but might as well go lower and stay a little cooler, IMO...
