mine was the same at first. turned out to be the boost safety changeover valve. start at the banjo bolt on the manifold, remove it and clean it. follow the line to the boost changeover valve and remove the line. blow through the line to make sure it is clear. remove the other line from the safetly changeover valve then remove the banjo from the ALDA. blow through this line. then attach a clean line to the valve, apply 12v to the valve and blow through it. since mine was bad 12v caused it to click but no air went through, not sure if it defaults to open or closed but whichever it is the 12v should change it. if you cant get air through it thats your issue. connect the manifold line to the alda line with a rubber line and test drive. this disables the overboost safelty so order a new valve.
