My other truck is a 675rwhp 2004 Ram diesel and it does this pretty badly with the larger injectors and programming I have in it.. anyway, as timing is increased, especially at low rpm/high load condition (like off idle or tip-in at cruise) you will get some rattle as the rpms increase to match the timing in the map.
Hope this helps some.

Welcome. Impressive what you guys are getting out of those trucks. Real trucks.
I watched some dyno runs that Ken Imler in sacto was running.. CRAZY power.
(FYI HPCR = High Pressure Common Rail)
I look forward to the day folks are under the hood of these DMEs, and you can change maps, etc...after the warranties are done!
