Thermostat doesn't make any different to the upper temp of the engine (assuming it's not stuck). The thermostat temp is just the rated temp before the thermostat opens fully. The thermostats purpose is the help bring the engine up to normal operating temp. It has no function in the actual cooling itself.

I would take a look at your radiator and water pump.

Also have you checked your ignition timing to make sure it correct. If its off that can cause an engine to run hotter than normal.
