C13 high egts ....what am I missing.....

I know this will sound redundant but go back and retighten ALL the clamps on both turbos and the bellows too. When I replaced both on my C-15 the mechanic told me to run it a week then retighten when stone cold (after sitting 24 hrs). I did that but still low boost and high EGT's, and high water temp, checked and rechecked everything you did and nothing worked. Mostly out of desperation I rechecked the clamps and loose again, short story it took 3-4 weekly re-tightening to get them to stay tight. Also you did not mention anything about the pre-cooler,(does it even have one? I don't know a whole lot about C-13's) You might want to check it for restrictions. Does the high pressure charger make any heat at all? If not, that is probably the source of restriction. I hate to be the bearer of bad news, but on mine it took 2 trips to Cat to get 2 good turbos.

 

Might sound silly but are your air filters clean? You may have a bad injector leaking fuel into cylinder? If you have turbo boost gauge, are u still getting normal boost level?

 

What flash file is in it ?

 

Yyeah i would recheck everything that had been done. If a heart surgeon can leave tools in a chest cavity than a mechanic can tool behind too. I once found a rag in my air filter. Just sayin'

 

Did you do a injector cut out. Maybe ones slobbering.

 

Rob - my C13 maxes out at 63lbs of boost after the tune.... that's a heap'o boost!
