No it would not be. What I said above is what needs to happen. If the 2350 turbo is worn out then replace it with the same cm2350 part# from cummins. The 2450 turbo is not going to be 100% compatible with that 2350 ecm.


And no for the EGR staying on, and the rest of everything off. That is a completely dumb idea that serves only to soot up the engine for no reason. The components can be left in place, but It all has to get switched off.
