What is your boost when it is doing it? - Pyro temps?

not sure, there is no gauge that shows boost or temps.

there is no engine light on either and no warnings so up.

cummins said there is no way to manually adjust the timing on a newer isx like mine and that the ecm was updated last time it was in there.

they called there specialist and the guy said call paccar, paccar said it is a drive line issue because it has a slight vibration all the time and reverberates through the floor like a u joint.

ive had the drive line checked a million times.

so know im going to have a driveline place take the shafts completely out and see if there balanced,carrier bearing,rearends etc

if they cant find something its going bye bye lol
