Hi everyone,
I have searched for threads all over google to try and find the answer to this. I already have an aftermarket boost gauge set up in my 33 gtst, however I am almost certain when I purchasing the car, which was most likely about a month ago that the factory boost gauge was "working". By working I mean that when I turn the ignition, the gauge will start up and sit at zero and move up and down when I am on or off boost. However when I am driving the gauge does not move what so ever but does move up to zero when I turn the ignition. It is if is the gauge has power but it is not sensing boost. Could the sensor have been removed when the aftermarket boost gauge was fitted? This is my first turbo car and I do have lack of knowledge, which I am working on .
Thanks
Sean
