"90 to 100 range"? I trust that's °C, meaning 194-212°F. That's okay, though not great.
Regardless, I believe a 165°F thermostat means your engine runs too cool. While that may be better for power, it increases engine wear - though most of us will never drive our cars enough that such wear becomes a significant factor.
