I have a 2005 with the bd pmt and right when i start the truck up i get "Initializing Communication" message over the main screen. I can see the parameters and and power levels i just cant change the power levels, and none of the parameters change. I contacted bully dog and they sent me the block that connects on the OBD2 and said that should be it, i just tried it and that didn't change a thing. Plus its stuck on extreme. so any help would be great!!! thanks!!
