99% of 4.0 applications should run a 195 degree thermostat.
Buy your stats directly from Jeep for the best reliability and STABILITY of coolant temp.
I buy plenty of aftermarket parts. I buy my thermostats directly from Jeep.

Could be alot of things, did it stay at the right temp before you changed the tstat?
I would never let it go above this red line:

I always verify using an infrared point and shoot thermometer pointed directly at the thermostat housing. That gets you close to the actual coolant temperature.
Don't want to be chasing a ghost.....test.

There CAN be some inaccuracy between the coolant temp sensor and the dash gauge.
