Check the thermostat. The wrong style thermostat can lead to problems like you are describing. Use only the factory style.

 

front mount oil cooler?

 

What is the size thermostat?

 

54mm

 

Overheating on normal highway driving, and not in town, is a bit unusual. Check the thermostat, belts, waterpump and fan clutch.
