How do you prove to the dealer that it was bad out of the box? Or do you just eat the cost and buy another?

Whenever you buy an ecm,.. ALWAYS have the stealers#it flash it with your trucks program before you get it. It costs a few hundred extra to have this done, but you can't be blamed for a bad ECM (or program).
it was mentioned here: http://rawze.com/forums/showthread.php?t...7#pid40577

also you should run the truck with that factory program for 10 minutes at bare minimum,.. but perhaps longer if you need to ensure your problem got solved ... before putting any custom program in it.
