Did this start after you flushed it ? If you pull over and idle does it cool back down ?

Just a shot here I've had similar problems with different rigs that had new radiator pumps etc. Two things come to mind that are easily missed but do have an impact first is the thermostat if its sticking its not allowing high enough flow even if its new its possible for it to get stuck also the cap on your radiator may not be sealing very well and not keeping pressure. Built up which hinders flow. Just my experience I know these are small things but they do help hope u find the problem good luck

You're making that motor work pretty hard, you might have to look at a high-flow water pump.

I've got a 91 just got 3&a half inch lift in 31it runs 210 all day so I considered pretty normal 10 degrees over that I don't consider would be very much check the simple things first radiator cap thermostat Exedra if everything checks out fine you probably have blockage in your radiator or you're just really over working engine and need a higher flow water pump. You could always just remove the thermostat if you're not driving it on roadand see if that helps at all because even though the thermostat is open it doesnt let the water flow as freely as not being there at all

I'm thinking someone doesn't understand the concept..."just get that nasty old restrictive thermostat out of there."

Just for something to look at, a search will show that some have found the 3-fan electrics inadequate for some situations.
