185-200 temp a 180 stat would be good.

166-176 temp a 160 stat buts that pretty cold.

I am using the Hypercrap 4026.

It sucks, turns my fan on after about 3 min of operation from cold and then it stays on until I turn off the car. If I start it warm, it never goes off. I am going to get one for a GN. I hear they turn on at about 190-200*.

I have been using the hypertech switch with the 176 on 166 off for a few years now. I have a 160* thermostat. Everything works as advertised. I guess it being warm enough may have to do with where you live but I have never had trouble having enough heat for the heater.

The only problem i had with the switch is that once i put on my headers the big 'ol connector that they use was too big. I am thinking about relocating it to the driver side.
