Excellent. Those are about where my temps are at with similar ambient outside temps. Now, if you really want to put the icing on the cake, wire up your aux wp to come on at 91°C and to continue to run during shut off until temps are back at about 85-87°C. You won't regret it. I've already posted several videos of this in action. This will keep your engine from heatsoaking and peaking at 120°C during start up after driving and parking the car for a bit.
