Any experience with 380hp mpfi conversion kit?

BTW, my understanding is that if the PCM has ever been in a rig with a BCM that has VTSS, the switch is thrown in the PCM to always look for a signal from the BCM that it is ok to run. This is from the FSM.

So if the PCM's are used and had been in a truck (or other) that had VTSS, then I think you are fighting with the security system and need to have it removed (if possible?).
