You can diagnose that with a temp gun too. The entire cooling system will heat up properly but won't level out. Temp will drop across the radiator and there will be no crazy hot spots on the cooling system but the exhaust manifolds (and heat crossover if used) will be scorching hot.
That's when you start looking at the tune.
true! But he will have to drive the car more than 10 minutes to do that.
