Did you manage to sort this issue out mate? I've just been fitting my Indiglo's and my fat fingers accidentally pried the rev needle off lol When I remove the needle and set it back to 0, it stays there (car off). But if I wind the needle out myself again, it rests at approx 2-300rpm. I haven't tried starting the car yet to see if it corrects itself, anyone think it will or do I need a new tachometer?
