Cummins ISM not reading boost correctly?

[in2trux]

There is a good amount of condensation at the egr but the Delta P should be dry.
If it is wet and hasn't been replaced, moiture isnt going to help anything.
If you haven't replaced it, I would. Next is figuring out where the excess moisture is coming from, possibly leaking egr cooler?
When you get it on insite, make a note of voltages and values of key sensors.
You might pm gearhead or Unilevers for more help or remote tuning.
I found the Ism to be very stable and reliable and is my 1st choice for class 6 or 7.
