So, I continue to have some issues since having the EGR delete done earlier in the spring. At the time I noted that the power was down, but in the cool weather the EGTs seemed in check. Now that the warmer weather is here, I am seeing EGTs that are about 150-200* higher than normal. Just as an example, I was coming home from camping this weekend (about 10K lbs with my camper on the truck) and hit 1400* while passing a truck and trailer up a mountain pass with a tow tune.
Engine temps never move above half which is a good sign. Now, I did put a winch bumper on it a couple of months ago but I tried to make sure there was adequate airflow into the grill. Maybe I need to make some sort of deflector under the bumper to deflect air upwards. Anybody have any suggestions? Air filter has less than 7K on it and all boots are tight and don't appear to be leaking. I have been having more and more starting issues lately also, which I suspect is the FICM telling me it's time to be replaced. Could a bad FICM cause high EGTs? I just ordered a Scangauge II this morning to help monitor some stuff to see if I can figure out what's up.
