Been like that almost 3 years now though without issue. Could use a bit better charger though as starts to get warm on egts on a long hard pull

what was done ecm wise just reprogrammed the 870 ecm? or did you get a 570 ecm on it
what i want to do is basically make the engine a 600 sig preferably with a cummins program on it
it must be more complicated than it is in my head cause noone or not very many have been doing it. for me it would be cheaper and safer?

Tune was done by a member here. Just swapped manifold and turbo with sig 600 parts. It did start as a factory 565 though. Which helped. If your parts are still good, just tune it. Not sure what your goal is
