of the turbos. Safety boost won't throw a code. A FAULTY sensor will throw a code but one just sending false alarms is considered to be working properly by the ECU and no codes will be shown. I would strongly recommend getting a new engine harness. I replaced mine when I had it rebuilt and I think that was one of the best things I could have done for the car. Get your stock sensor wired back up. Even with a boost controller it can still retard your timing if it goes into safety boost. Then your running higher boost levels with a retarded timing, not an ideal running condition.
