RE: RPM 's Bounce
All my cummins have done this. My old cm870 and the new cm870 long block with all new actuators, new ecm, programmed by Mommaburt, overhead ran correctly, cam timing verified, new fuel pump, new turbo and actuator, new actuator control module and system 100% good, replaced the speed sensor... basically everything i could imagine and everything i could gather from here was done. Except fully rebuilding the IFSM. Other than that I chalked it up to to what Signature620 said.

My cm871 does the same thing but I haven't verified everything I did with my cm870's so I can't vouch for the nature of the beast diagnosis yet with it.
