Had this installed in my car when i got it. Was set to 15.6psi but everytime you open the taps it would only hit max 8psi. No error codes no det code. Just ripped it out and installed 1.0mm boost jets. Boost guage on the gizzmo ibc now read 11.5psi. Incorrect installation? Any ideas?
If the stock boost solenoids were connected then and now there's your answer. Boost controllers need them disconnected and boost jets need the stock solenoids connected to work.
