My 04 ccsb has been seeing some high egt's lately. I swapped out my 04 turbo for a 03 and now while cruising at 70 in my row tune I see my egt's at 800/900 on the flats. If there is any increase in grade at all I'm seeing 900/1050. I'm pulling my trailer this weekend through some pretty good size mountains and don't want them getting so bad I would be creeping up hill. Any thoughts or ideas on what the issue is? I don't have a boost leak everything is tight. The trailer weight will be around 10k. Do I have anything to worry about?
