CUMMINS SWAP 2250 to 2350.

[SquareOne]

I can def attest to the procedure Rawze is referring. I currently have nearly 180k on the setup he tweaked in Feb/March of 2019. ----> 2250 modded ecm program running a 2350 engine. Very interesting the details that make those 2 engine types differ and like he mentioned before, most would never know as the 2250 ecm would initailly appear to run the 2350 with no issues.
