I don't know what temps mine run at, I don't even have a temp gun, I tune to
performance and smoke, I spit test it to see if excessive but other than that....... lets just say after a 30-45min final it's pretty warm
but no loss of power at or below mid tank at any time durring that time,
(but if that happens then your top end is too lean)
