I overnighted my tune got it today just installed it and truck runs like crap! I called Allen and he and John where both busy with customers. I went to the local shop they did the crank relearn and its throwing a P0200 code, something about fuel injector rail? I drove it home and put the stock pcm back in until I hear from someone.

oh also have the harness for electric fans, its not turning them on? I touched the blue wire for pin 42 to the ground and they both kick on. When I put the wire in pin spot 42 and plug it into the computer it does nothing?
