80c is fine
re settings try taking some of the boost and or turbo off.
I am now running a GM 21.5 and found that if I run the maximum 64 the motor gets hot (have had a 120c)
taking some of the boost and turbo off made the car quicker and a lower temp, so a double gain
also start rpm makes a big difference try getting the boost coming in at a higher rpm
