As far as I know it is a stock PCM. I bought the truck used, so cannot be 100% certain.
I have a trailer brake controller on the truck, I infomred the guys HP, did not concern them. Only other item I have is radar detector. Disconnected that to make sure it was not causing some cosmic interferance.
I have nothing else connected to the truck, stock stereo, stock batteries, stock motor and tranny.
Working on a few things with them, so we will see what comes of it.
Thanks!!!
