Since you have cummins insite, monitor the VG position commanded and the VG positiion measured and see if they are matching when it is acting up. Also pay attention to the position measured and see where it is going compared to when it is running right. A miss-match of more than about 1-2% is not a good sign. 5% or more of mismatch and it is definitely the turbo acting up.
