Can an ECM from a dodge 24 valve be put in place of an ECM on a 24V cummins in a ford F650 truck? The Ford or cummins ECM on this truck is governed at 2600 RPM which makes it horrible to drive. I put a Van Aaken smart box R which helped greatly, but you cant get enough RPM to pull a hill or even get up to highway speed in a reasonable amount of time. Cummins offered their performance help for a mere $2000, owner said no thanks. OR if this isnt possible would swapping to an HY35 give more midrange to compensate for the lack of RPM?
