how many rpms can a duramax take without floating the valves and doing a lot of damage

: lb7 rpms keith_2500hd 09-09-2005, 11:34 PM think at least to 48-5,000 rpm down hill, don't think engine(ecm) will let you past that. don't think ecm will let you past 3,400rpm level. IBDMAX'IN 09-10-2005, 01:03 AM With the "Soup" and some other programs you can go to 4000rpm under power and I haven't heard any problems yet. I heard the d-max was a 5000rpm motor, I might be wrong but that's what I remember.
