you need to take the PCM to someone that can put the factory tune in it for the engine/vehicle you're going to run it in or a suitable vehicle for the application you're using.

they can load a stock tune on it
A lot of CarQuests can do the load for you, too.

Nope. I've always run the 411 pcms, faster processors and more agressive base tunes, plus I believe you can control electric fans with them vs the earlier PCMs.

pcm installation
So I installed the new/pcm the junk yard was able to match the serial #. I went ahead and relinked it and started the truck, it did start but miss firing of course cause of the cam and stuff,my question is can I copy and paste from the other tune. Or should I input the value my self.

So I finally got the truck running, one problem on my dash it wont show me the mileage and the gear. When j installed the pcm I relink it with the vin number it came with, and disabled vats. Could that have something to do with the problem.please help.
