Was this cal swap right?

On smaller engines, it is not unusual to have a different program than is listed on Quickserv/th ecm. Manufacturers often do this, and the only way to find out what program belongs in it is to ask the vehicle maker instead of looking it up on cummins wwwsite.

- Also if you have emissions stuffs unplugged and it is not throwing codes for it, then it most likely has a de-mandate file in it. Copy the program from the ECM and e-mail it to me for a proper review of what someone has done in there.
