The display on the guage had always only ever shown -1.0 but I was expecting it to move once I had the car back on the road and was giving it some beans. When the car fires up it moves then settles at -1.0 and never budges however I drive the car. The turbo is spot on and certainly comes in and out.Am I missing something or is there a sensor that is bust/faulty?
Cheers
