odd thing going on

[stevesparts]

Well here's the update on this one...
Since this still has a warranty on it i took it over to Cummins in billings mt, and they got me in quick(SHOCK!!)as the one down in Henderson co. was swamped (week to wait) so i told them what was going on,and after a bit they came back with the skinny on it.
it turn's out it had a bad actuator and ......wait for it.........a EGR valve.(SHOCK) explains the egt temp. So all is well...for now, time to get this over to someone to tune it up as the warranty will be up in 20 days or so...
