No it is a stock Thermostat in my VS. Did a complete cooling system clean flush when I got it a few years ago & replaced the Thermostat with another stock one. I may have drill a 1/8" bleed hole in the side ring at the time, can't remember now. Pretty sure the Thermostat had 91 degrees stamped on it.vs ss wrote:
Going by your driving temps I take it your running a lower temp thermostat? If so I would drop your fan temps down so there's not such a big difference.

Thanks for all your replies guys, very informative

I will give the fan check a go too.
