Umm, the 250HP isn't a CRD is it?

And there are about 9 computers that control the isn't just the one on the block. Even the dash has a computer that controls the engine to a point...I know this for a fact as I just had mine replaced.

well considering all cummins offered in 2003 were common rail then yes, its the low output version of the it.
The 2003s weren't all CRDs...unless it was a conversion, I looked at a 2nd gen "style" 24-valve in a 2003 3rd gen.

But regardless, I doubt changing computers will cause you anything but will reject the other...they all need to be "synchronized" if you was a PITA getting my dash cluster changed (it is also a body computer in the CTDs) for that reason.
