Im getting ready to get a Edge CTS and was just wondering what all of my temps and pressures should be at or about so when I get it I will have an idea of if my truck is running fine or not.
My truck is a 2005 5.9l Cummins stock except for a 6" lift with 35" tires, magnaflow muffler, and an air raid air filter other than those nothing is done to the truck YET!!!!

 

I didn't put a boost guage on my 2004.5 as I did my 2001 but I did put a exhaust temp and trans temp for my 48re. I didn't see what kind of trans you had. I think I will consider a after market oil pressure guage as I 'm a bit leary of the factory guage. The concensus seems to be on egt that 1200* is OK and going a bit over for passing or hill climbing is also OK but I wouldn't want mine to go over 1300*. The most used max temp for automatics is 220*. I have a pan mounted sending unit that has never gone over 190* and usually doesn't see 170*. There are those that believe that pan mounted sending units for autos are wrong and say that the output side of the TQ is the correct place to take the temp as it's the hotest. Don't know but if you have an auto and tow heavy, as in over 5k, I would strongly encourage your getting a trans temp guage and monitoring it especially at low speeds on hills.
