It Never Ends!
I started running Torque Pro today on my r56 cooper s. I noticed engine temp stays around 105-108 degrees C. This is far too hot, right??
Coolant system is working with no leaks.
I think the thermostat is not opening at the right temperature.
Can the thermostat be changed, or must the entire thermostat housing be replaced??

Pressurized coolant can take a higher temperature than coolant in atmospheric conditions. This is why you can run a car cooling system above 100 deg C.
Just a tip that I learned the hard way, the temp sensors in at least the N18 engine is in the head. When coolant is lost due to a leak the sensor will see an air bubble that may not actually represent the engine temp. I over heated the first engine in my car to the point of full destruction without ever receiving a warning that it was over heating or low on coolant. It drove perfectly fine and normal with no warnings until the valves seized and crashed into the pistons. The point that things started to seize, the car went into a limp mode that lasted long enough for me to pull off the highway before the engine stalled.

I was on a motorway in the middle of Wales, here in the UK. That's like deep nowhere.
Why don't they fit coolant flow sensors?
