I pull a heavy load once in a while, maybe 8-9000 lbs, want to make sure i am not working her too hard, what is safe temp for engine, tranny, exhaust, i have an edge system, has tow mode. But just worked her hard this last weekend. Anyone that knows good temps for all let me know, want to make sure i run it right!

at that weight i wouldn't be to worried about the temps going to hot i double that and still stay at normal temps my trans will heat up to about 230 but goes down quick once i sit and unload the trailer and it about 15min. But i would say around 210 for the engine should be below that and below 200 for the trans

so my edge chip has 4 numbers on the screen, the upper two are exhaust and engine temp right? or is it tranny temp and exhaust temp? and the bottom two are boost and load? is there anything special about those bottom two numbers and how they should read? :)
