over heat HELP!!!

my 05 will over heat going up grades towing or not. used to spit and blow. just replaced the radiator (had a small leak), fan clutch, thermostat, and degas cap. when done i completely flushed the cooling system. now it runs cooler but going up the grades it still warms up almost to the red line but doesn't hit it, it will sit there for a minut then it will drop right back down(affected by rpms). you can here the fan running when it warms up. just had egr cooler and oil cooler replaced at 99,500 miles. now has 105,000 it was studded at 75,000 along with new heads and gaskets dealer has checked for HG's at time of EGR and about 1000 miles ago both times said they where good. only part left is i think is the water pump, is there any sensors to check to. what do you guys think? any help appreciated.

where did you get the thermostat? I have had a few times where I throw a brand new thermostat in from advanced auto and its overheating: exchange it and everythings baack to normal.

I would throw another one in. Theyre stupid cheap so why not try? especially before doing anything pricey and time consuming like a water pump

after all this it still overheats in any tune. how ever on a stock tune i couldn't get the needle to even move. is it possible for my tunes to have gotten corrupted to cause this?
