Hey guys, I just removed a Bully Dog GT tuner out of my 2012 Ram 2500. ThenI replaced it with a H&S mini maxx tuner, after I installed it the egt's read for a little bit, but then froze. So then after turning the truck off and in again it worked again for a bit, then froze again. I have got the probe installed and wired the way the instructions called for, but this still seems to be happening. If anybody has any ideas or if this has heppened to anybody else can you please give me some advice?
