I’d like it to run under 180 ish so my fans are not on for highway runs. Dont want the fan on for 30 min constantly. I can adjust the on/ off but I don’t want this thing to be at 200 on the city streets
Yes, you do. The modern Hemis are DESIGNED to run hot. My Challenger ran 200-210 highway and 210-225 in traffic. Even in the dead of winter, once it warmed up it NEVER ran below 200.
