Default ecm

My dad has a 2003 4x4 auto truck that is running rough and throwing a P0306 code. I tested the injector and wire harness and everything tested fine so I went ahead and replaced the #6 injector with a new one from cummins but still didn't fix the problem. So we took the truck to dodge and they said the ecm needed to be replaced to the tune of $3500. I have found reman ecms for anywhere between $500 and $1200 or a mopar ecm for $1800. So have any of you replaced an ecm and have a company that you would recommend? Thanks, Bryce.
