Ok so the deal is is i just had head gaskets done and head studs and oil cooler i have a egr deleate form middland diesel in fargo nd what they do is weld a plate in place so that if you are driveing in a state with emistions or something it looks like it is still there if any one now what they are looking for on the dot side of things i drove it about 200 miles and now it is over heating but not loseing coolent what are the chances my thermostat is not opening or something alone that line of things or a bad degas cap but it is not boiling over or anything

Wow. That is ONE LONG sentence... Can you confirm what your coolant temps and oil temps are?

Ok so an update on what happened today. I called them and they were talking thermostat or sounded like a fan clutch. so they replaced the thermostat and thenthey took it out and drove the hell out of it they said to try and get it to overheat and could not. But the guy said man that sct tunner makes that 6.0 run like a rapped banchee he said that is the best running 6.0 he has seen. My delta's are with in 5 deggets up to 226 is were my sct starts flashing at me but get up to 230

Yeah, it could definitely be caused by a bad thermostat although the factory t-stat's would fail in the OPEN position, which shouldn't cause it to overheat. Maybe yours was replaced before you got the truck with an aftermarket t-stat?
