I've looked all around but couldn't find an answer, I'm changing my thermostat & bought a 180 dgree, after reading the different threads, people say not to go with the 180 but to stick with the stock 190ish, if I don't have a chip? I live in the california desert & heating up my engine is not a problem. My problem is that my SC runs very HOT... on or past the M or regular driving. It's quite possible it's the original thermostat, so I'm wondering if that's my actual problem?
