Any experience with 380hp mpfi conversion kit?
Did you change the IAC and TPS connectors to get this wired in the first time, or did it plug in to the factory parts? This PCM is intended to run with a four barrel throttle body.
Just thinking if anything else could be making it look like a security problem.
Do you have a scan tool of any kind that would show sensor data? I would connect data line wires and check data before sending it off for testing.
